For commercial entity that is mostly true. Let's Encrypt is provided by a not-for-profit entity and they tend to be benevolent.
Since you seem to be pre-installing and configuring everything beforehand I'd recommend looking into OpenSuse instead of Mint as it's an enterprise oriented distro. It has a lot of easy to use gui and cli admin tools (yast) that make life a lot easier for maintaining the distro.
FOSS developers don't develop distros. Distro maintainers package that software into distros. Linux, KDE, GNOME, systemd, GNU software etc are just single pieces of the puzzle developed individually.
The distro is closer to the old proprietary OS. So the enduser just has to learn other “new” software, the OS doesnt demand a learning curve but just replicates the Win/Mac experience.
There's always a learning curve with new things (software or otherwise). In case of Win why would we want to go back in time in usability? E.g. Cinnamon and KDE are far superior in UX compared to Windows. Also in Linux distros you can actually fix problems unlike in windows.
I've been using Linux as a daily driver since 2018 (thanks Valve and Proton) and in my experience things just work (if they are supported) and thing like headset don't just randomly stop working because reasons unlike in windows. In windows you then run some troubleshooter that can't fix it, reboot several times while praying to whatever gods you like and hope for the best. If that doesn't help you start searching online and only find vague instructions that might help but no solutions.
Missing software compatibility
What compatibility? If user insists on running some windows only software it's expected to run into problems.
the need to fall back on the commandline are just some of the problems.
So? Even windows and macOS has a command line. It's easier to help with problems if you instruct them to run some command (though running random commands of the web is not really a good idea security wise) then trying to navigate them to some gui which might not exist in their distro. Even in windows users are told to run commands in the command line to try and fix problems e.g. sfc /scannow and dism <whatever>.
Now you are thinking: But just install Linux Mint and they probably do most of the things in their Browser anyways.
In AD 2025 this is true in most cases. People just use social media, some webmail, youtube, read news etc. The OS is just there to start the web browser.
Any idea how long support will last for the 8?

As they use imap, caldav and carddav for email, calendar and contacts you can use any app you want e.g. thunderbird.
Edit: They even have a moving service so you can move your existing emails from gmail to them.
A solution is not to use any product, service or software made by MS or google.
I would quit youtube immediately but there are some good content creators that don't post their videos elsewhere and I do want to watch them. Gladly there's FreeTube for that.
Quite true. Linux and all modules loaded into it are GPL licensed. The userland and tooling on the other hand can be licensed however. They are free to close source on anything except kernel code.
Doesn't have a significant impact. Using Telegram (though third party OSS client called Forkgram) and Signal without Play services on pixel as well.
Use MS Edge
Use Chrome. Edge is a minority browser (has a market share of ~10 %). Using chrome though gives all your data to google ( so not recommended).
