Curiosity, back around 2010 before I was a teenager. No clue how I heard about it, but the concept of replacing the entire operating system was fascinating. I figured it must be really good if it was such a well kept secret.

A few years later, when I started to learn programming, Linux was the obvious winner. The online course taught C in a Linux environment, and I was amazed that the default Ubuntu build at the time had everything built in, whereas a Windows equivalent required visual studio and licensing adventures.

It really stuck as a daily driver after Windows 7, where a clear trend emerged: Windows got in my way, Linux got out of my way. Simple as.

I heard about it off and on, but this was the days in dial-up and downloading an ISO to install Linux was too expensive in time and bandwidth . I had discovered at my local Office Depot, a Mandrake Linux box set so I splurged on that and got my first taste of Linux then. I also was able to surf the web and learn how to install it manually, but it didn't make any sense at all and was too complex. For Mandrake, I didn't care for it. It wasn't until later on when I started working with hosting sites, that I got used to Centos and Ubuntu for servers. I even had Mac OSX for a while, which taught my about the directory structure, but I went back to Windows until around 2015ish when I jumped ship and went to Linux fulltime. I worked technical support and the servers were Linux based so I had learned a lot more doing that and got very comfortable with it. I then jumped through different distros to where I am now (Arch). I firmly hold belief though that Arch isn't the best and no distro is truly the superior one. Instead, whatever Linux distro you use, if it does what you need it to do, then so be it!

To answer the question though, what pushed me toward Linux was really the whole push toward Windows 10 being more loaded down with the pushed tracking and advertisements that comes with the Windows Territory. Plus - I grew to love the command line and it's sort of my second home now.

Windows is boated and eventually becomes unusable or unsupported.
Linux has no such issue.
That was my initial reason for trying it.
Since then I've revived countless computers with Linux.

work requirement, amphetamine-driven endless curiosity of staring at commands and man pages, interest in programming, initial allure of the concept of copyleft

It was PHP and Laravel.
I started doing fancier things with websockets, redis, cronjobs etc.
Anything "designed for" laravel hosting wasn't cheap. So, I learned how to get a VM going and set it up for webhosting.
Windows is still my daily driver due to Office, Visual Studio and gaming.
But I have a bunch of VMs and servers, and they are all Debian.
I enjoy Linux, but I haven't gone whole-hog into a desktop environment or whatever. Everything has been CLI based

My computer was trash. I migrated out of necessity. It took 40 minutes to boot into Windows XP. Old-timey Lubuntu kept that computer alive for another 5 years.

When I got a real computer, I found that using Windows was unpleasant -- So when Proton started to mature, I switched back to Linux (cuz hey, vidya gaems).

... Then I became an adult and the political radicalisation began.

I'm not "obssessed" so much as I am politically motivated, so I guess I'm an evangelist in a way. If there were ten other mature open source operating systems I'd shill all of them. As it is there's Linux and BSD. So those are the ones I shill.

Generally I'll pester anyone willing to listen to get as far from Big Tech's walled gardens as their life necessities allow them.

I'm not a tech person, I think most Linux people are? Instead I'm just someone who studied basic sociology and history, and can see the kind of power that walled-garden tech can (and HAS, in recent times) give to very few people.

Privacy, Windows 11, and the fact that my system is more stable running Linux. I could count on a BSOD happening once or twice a week due to a driver issue with Windows 10. I still get strange crashes on Linux, but much less often.

Cut throat environments!

I'm a primarily Windows systems administrator with about 18 years of Iat field experience.

While I initially played with Linux to get war3 running back in the day of mandrake/mandriva on and off it was only a curiosity.

But during covid with work from home windows became synonymous with work. I couldn't sit and use my personal pc any more without a alert, a message, an email, a system in my tool stack (MSP employee). I couldn't relax.

Then I decided to buy a second ssd and I ran just some Linux, I think popOS. I administrate and use Ubuntu servers at work and in labs a lot, so it was familiar enough to get around and wine had improved a lot. New things like lutris showed me that running overwatch and starcraft2 was possible in a wizard.

Next I learned about proton and the upcoming steam deck and the compatibility modes in steam and except for some yakuza games almost my 400 title library was unlocked in Linux.

You know what doesn't work in Linux? Almost all my systems remote management tools. So now if I boot Linux I'm not working.

I'm not really a Linux advocate. I'm not a Windows advocate. I'm not a mac advocate. Right now I design solutions for companies and while I'm biased I'm tools to tasks minded. The right tool for the job for the workflow, that integrates correctly, and improves productivity and enjoyment of the task.

Linux fits that for my case for personal enjoyment, but can't possibly fit my use case for my job. It allows me to be disconnected and relaxed. It gave my personal pc meaning again in a covid and sometimes post covid world.

I borrowed an installation CD from the local library around 1998. It was RedHat 5.x, and I started messing around with it due to me being interested in alternative operating systems. Before it, I had OS/2 Warp 3.0 in our IBM Pentium 100 MHz family computer which didn't really do it for me to be honest.

It took weeks to get anything working with Linux. I went to the library, borrowing books. In our middle school we had an internet connection, so I utilized it to learn how to configure modelines correctly to get X11 running.

When it did finally run, the default window manager was FVWM95, almost like Windows 95!

I used OSX a few years in the power PC times, just to switch back to Linux around 2008.

Edit: my real love for Linux started when I got Debian running. RedHat didn't have anything comparable to apt those days. You needed to download RPM packages manually with all the dependencies, while apt just worked with one command.

A friend in high school gave me an Ubuntu live CD and told me I should try it.

Windows used to break all the time, Microsoft was evil, that Ubuntu thing showed up.

I wanted to see what the fuss was about after windows 11 came out, because I was sick of Windows intrusive UI and shady business practices.

I still use windows for some things, but now I duel boot to cinnamon and it is my daily desktop driver. I vastly prefer the clean interface and speed of Linux over windows, and I now play most of my games on it too. I was shocked when I realized that Elden Ring runs great, and looks better, on Linux while it was unplayable on windows at release.

I also installed Fedora to my surface pro after a windows update made it impossible to use without severe slowdown. I've had my surface for 6 years and it runs great on Linux.

The only downside to Linux is that, as am artist, the apps are limited. Blender is fantastic, Krita is catching up, but there is no way to use clip studio, harmony (toon boom, storyboard pro), or Zbrush (yes I can sculpt in blender but it is not quite there yet.)

I was massively obsessed with all kinds of computer tech in the late 90s to early 2000s, and read about Linux at some point. I tried a few distros* and enjoyed playing around with them, but a combination of them being a bit rough, and needing to run Windows for games and to support people for my work meant that I couldn't switch.

Over the years I tried out different distros, and even had home servers running before it was cool (obligatory 😎 ), but because I knew Windows inside out, the things that I was trying to do with Linux were much easier for me on Windows.

A few years ago I bought a few older laptops that ran like dogs even under Windows 7, so tried dual booting Mint. The laptops still struggled, so I had to switch my wife's back, but I persevered with mine. I upgraded to new to us refurbished laptops and put Mint on mine again. I also switched our media server to Xubuntu at some point over the last few years.

Windows 10 was getting slower and slower, even though it was a 7th gen i5 with an SSD and 32GB RAM, so I bit the bullet and wiped the Windows partition. I upgraded the RAM and added an SSD to my kid's laptop and did the same. My kid had to have Windows on their desktop because of the problems with Roblox, but the success of the laptops has lead to me dual booting my desktop and trying to switch full time. I've got a batch scanning job to finish under Windows because I can't get the colours to match under Linux, and I've got a few thousand photos to process in Photoshop, and then I'm hoping to switch full time.

I'm not an evangelist by any means, but I do wish that Linux had got to this stage a few years earlier, while I was the go to geek for so many of my friends, because I know loads of people who would have loved using it back then :)

*Hoary Hedgehog as an OS name still makes me laugh :D

Curiosity. Then starting development and figuring out most things non-MS specific assume UNIX/Linux based. I'm not obsessed at all, I quite enjoy macOS, and don't mind Windows too much for what I do with it, but it's my OS of choice for development machines, and any servers I control.

As a young tech trying to get started, Knoppix live CD enabled me to clean viruses and recover data for clients.

After years of using it as a specific tool, I decided to daily drive it when an older machine stopped accepting Windows Updates.

I still run Windows on my big rig, but Debian on everything Else.

Self hosting. I was using windows to host teamspeak and game servers. I first got into linux by switching my homelab to linux and running everything in docker containers and VMs. Then from there I started using it on a desktop and laptop as well. Started on manjaro for years. Then went to arch for a year or two. And now I've switched everything over to NixOS.

Interesting how there's so many answers here, but no mention of the one I came here for (and I thought would be most popular) : ricing.

I got into Linux when I saw screenshots of all the cool desktops people made with KDE, XFCE, and tiling window managers. Even Gnome looked sleek and minimal. After a while I got bored of ricing but I stayed for the ease of use as a developer

Username and password.

Well, my experience was always on and off: In the past, I always had my phases of trying it out, be it dual-booting, or outright replacing my OS, but always went back to Windows after a couple of months at most due to some software being Windows-only and both VMs and WINE not being sufficient.

But this year, with Windows continuing to get worse (built-in ads, the fact that it eats 60+ GB on a base install, etc.) and me needing Linux for uni anyway: I made the jump and thanks to the work being done with stuff like Proton for games and FOSS software now being good enough for general productivity, I'm happier than ever.

Obsessed? I like customizability and being able to tinker around, but in the end, it's a tool like any other.

I used Linux on my jailbroken Chromebook during school before and I slowly started using more and more of wsl when that came out.

Then one day a windows update which started automatically on my laptop ended up wiping the encryption keys, I lost all my data including a lot of organised financial documents. This happened while I was having trouble with wsl where it would just delete itself on my pc. Then there was the issue of my pc having an English international keyboard which I was unable to remove and windows kept switching me to it every 2 minutes. Which makes programming harder due to how it handles inverted commas. I ended up doing some regedit to remove it, but then all windows system apps stopped working, including settings. And guess what, there was now an update ready which I could not skip because settings won't open. And did I mention my laptop wiped itself again?

I did not have a single issue since I switched about 4 years ago, I never looked back. Not even for gaming, I exclusively use Linux and I am proud of it. And this is saying a lot, because I always mess up my system when doing random experiments for fun, but there is also always a clear way out. (I use arch btw, and rtfm really helps a lot)

I got this incredibly busted hand-me-down that was having issues running windows, so I installed Linux mint on it and then distro hopped until I started daily driving arch on a new machine.

Embedded Linux is such a huge part of embedded software in every industry. I've done a bit with build root but mostly Yocto. There is just no replacement for the Linux kernel. If I need to know how the kernel actually handles a platform driver, I can just look up the relevant source. This is just impossible with Windows (IoT or otherwise)

Curiousity, wouldn't say I'm obsessed but I'd hate to switch Windows now since I'm way more familiar on Linux. And I've satisfied (killed) any curiosity in Windows server and desktop in professional life

It was two decades ago, when someone gave us the CDs of Fedora. It was so very different than Windows XP. I came back to Linux when my school library had Ubuntu on their computer. I'm gonna ask someone to gift me Steam Deck upon graduating from college.

I was lucky to meet some real operating systems (VMS, Unix) before I got contaminated with Microsoft products. So when I first heard about Linux (some guy in Finland wrote a new kernel and showed it to Prof. Tanenbaum, and when he grows up, he wants it to become a full fledged unix :-)) I knew already what it is.

Im not into it yet.

But the answer is windows.

Curiosity. I was a curious tweenager, and I was already a bit of a geek at the time. I read about Linux in computer magazines at the time, and decided to give one of the free CDs a try - with RedHat 5.2 on it. To be honest, wasn't really impressed with it. I especially disliked having to recompile the kernel, which took ages on those Pentium 3s. But it got me exploring other operating systems, and I found QNX, BeOS and NetBSD. I was really impressed with with QNX and BeOS in particular - Linux felt quite clunky and amateurish in comparison. I especially liked the multimedia performance of BeOS, and the lightweightedness, polish and desktop responsiveness of QNX, which featured a real-time microkernel. QNX felt lightyears ahead of it's competition at the time. My first run into it was a free 1.44MB demo floppy that the company mailed me directly, complete with a full developer manual (which was completely wasted on me as a tween, but I still appreciated it and tried to comprehend bits and pieces). I was already into making custom bootable floppy disks at the time, so I was extremely impressed that they managed to fit in a full fledged GUI desktop, complete with a browser that supported Javascript (along with network drivers and a modem dialer) - all on a 1.44MB floppy disk! Till date I've no idea how they managed that. Even the tiniest of Linux WMs are massive in comparison and look fugly (twm), but QNX's Photon microGUI somehow managed to make it good looking and functional. Maybe it was all coded in Assembly, I don't know, but it was, and still remains, very impressive nonetheless.

I digress, but all this started getting me into exploring POSIX systems and distro/OS hopping. It was only when I experienced SuSE that I fell in love with Linux. Finally, I had a polished Linux desktop, with a full-featured settings/control panel (YaST) that made it easy to use even for a tween like me. And that's when I switched to Linux as my main-ish OS, with Windows relegated to gaming duties. However, I didn't fully get rid of Windows until Windows 7. I was actually impressed with the Windows 7 beta releases and was prepared to buy it at release, but... I wasn't expecting that price tag. I was hoping I'd get a student discount, but it wasn't applicable where I lived (or there was some catch, I don't remember exactly). In any case, I couldn't afford it, and I was really disappointed and angry at Microsoft that they were charging so much for it here, compared to the US pricing. And so, on the release day of Windows 7, I formatted my drive and switched to Linux full time, and never looked back.

My Mainboard had somesort of error, where Windows wouldnt Work, Linux did tho

I wasn't happy with windows vista's prformance and wanted to try something different. Didn't make the switch permanent for a decade because I needed games in my life but I always ran linux on my laptops when I got them.

I was on a Microsoft systems admin/engineer path for a while and an opportunity opened for a KVM/XEN engineer and I was the one only person in my office to accept the offer. That was back in the RHEL/CentOS 4 days.

After playing around a bit I got hooked and haven't gone back down the MS path since then.

First real terminal contact (except for limited use in macOS) I had working at a company which now uses embedded Linux in their product. After that I got in a situation where I had no computing device with admin rights running anymore. iPhone, iPad, corporate locked windows. Once there was the day I needed admin again, so I went searching and found an old iMac lying around, macOS was barley useable (low spec) and I just managed to create a bootable stick with it. Fast forward 2 years, I now have the old iMac of my dad with better specs running tumbleweed with Gnome, and I love it, with the right extensions, this frontend is very fun to use.

My boss at the time (I was a writer for a tech magazine) asked me to review FreeBSD. I couldn't get it to install (at all) so someone suggested Linux (Slackware) which was an insane idea at the time around 1995 or 1996. Slackware sort of worked, no sound and I had to do various really annoying things to get it to see my modem (which never really worked). But something about it was interesting and I stuck with it.

Curiosity, mostly. And Ubuntu giving away freebies.

Took me a couple years to get out of the "Why change a winning team?" mentality and my baby duck syndrome.

Less "get in to" and more "all my shit is so old basic things on the internet were not working any more if I left it running XP or 7".

Windows 11

I wanted to switch to Linux for several years because I was very sick of how Windows did things.

With Valve doing Proton and Windows 11 being a much shittier Windows 10... With rumours of it eventually becoming a FORCED update!... I decided to actually switch to Linux last November.

Haven't regretted it. Haven't used any other OS since.

Worked as a computer repair tech forever ago. We ended up with tons of spare parts and abandoned computers. I took a few home and looked for things I could use them for. Quickly found Linux and gave it a shot. It was perfect, I didn’t need to spend $100+ for a copy, there were tons of options, and I could do anything with it. Spent the next 20 years using it on every computer except my main desktop because of games. At one point I was 100% Linux and all I played was WoW using WINE. Now I’m back to 100% Linux thanks to steam and proton making a healthy chunk of my library playable.

Any time someone comes to me with an old computer my recommendation is to throw Linux on it and get a few more years of usefulness out of it.

Curiosity pushed me to try Linux roughly 15 years ago. Today it's simply the best option for me. But I approach it as a user, I don't posses any deep knowledge about how it works.

I taught myself some shell scripting and unix commands after being gifted an iMac running 10.3. I then decided I wanted to fully immerse myself, so I dual booted that thing with OpenBSD.

The installer back then was pretty barebones; I used a scientific calculator to set up the partitions. After install I was dropped into a root shell and had to recompile the kernel to apply the latest system patches, then set up my user account, sudo, and bootstrap the package installer.

Getting the latest Firefox meant compiling it from scratch, which took about a week. Setting up flash involved configuring a Linux emulation layer. It worked on most sites, but not others.

I began pining for the binary updates, native flash support, and huge package libraries available in Linux, not to mention the cool wobbly window cube that compiz fusion offered, so I made the jump to Linux.

I've switched distros and even switched to other unix-likes, but in the end Linux won for me.

I was being encouraged to learn programming by my brother-in-law, so when I was going through the lessons in the course he bought there was a section on Linux. At first I was thinking on how would I be able to install in a virtual machine but my brother-in-law in all his wisdom said "why don't you dual-boot". After some planning so I don't nuke my hard drive and flashing LMDE as my first distro I installed Linux and did the rest of the course there.

I've distro hopped 3 times since then:

LMDE (3 months) -> Ubuntu LTS (4 months) -> Arch (2 years) -> NixOS (2 weeks)
