Thanks for the correction.
It shouldn't be a difference, what Ublock and Brave and network based blockers such Pihole do is they have a list of domains that are not allowed to load on your system.
If they find that www(dot)adexample(dot)com is trying to load in your browser, they simply block it and the video continue.
Maybe the only different is the privacy itself that offer something like Libretube vs something like YouTube + Ublock. While using Libretube, you are only loading what is neccesary, you are not giving Google more information that you shouldn't, and while you using YouTube in Firefox for example you are loading all the cookies, trackers and that stuff, even in private browser with maximum privacy settings and adblocker.
I know this not answer your questions, but I was like this years ago, I wanted everything open source, everything in VM or container with minimum permissions, only open source drivers, only flatpak, and all that stuff. I was like that for 3 or 4 years, in the meantime I changed my email address to a provider with better reputation than Google, I stop using everything that was proprietary, stop using Google services. Even did the most stupid thing, deleting my 5 years old Steam account because "I don't need Steam to play, I can pirate games or play open source games so Valve or the companies can't access my data"
And what happened then? While I was happy owning my stuff, I don't have that much things to do on my system, can I play? Yeah, an pirated game through Bottles (since is sandboxes and pirated) but was a pain in the ass, the 50% of the games required at least 2 days setting up Wine to make them work, and I'm not an Linux expert but I know my way around. And by the way, at the moment I was using NVIDIA, and their open source graphics at the moment were shit, not sure how they are now, but you can't literally run Terraria, no joking.
And now that I mentioned NVIDIA open source drivers, at least at the moment you can't even play a video on Firefox because of the stuttering, I can't even try Hyprland or Sway, and even Plasma ran so bad, was so fucking laggy on both Xorg and Wayland.
Oh and the most cancerigneous thing: I distrohopped like 1 time a day searching for the distro with the most compatibility. How many time I wasted on this.
So I suggest you: Don't do that. Don't be me. Want to play? Why don't you set up a dual boot and let Steam only in the secondary OS that you don't want to use? If you want be sure that Steam can't access your other OS, you can encrypt the whole disk or partition. I can tell you, for sure, that videogames are pretty delicate and when you try to run something over different layers, something usually can break and you don't know why.
Holy fuck thanks for sharing, I always wanted to use my terminal on Linux just to show my friends how I can type "ls -l" and look like a hacker!
I remember when I started on Linux and the open source world in general that the "Releases" button on Github was like an omnipresent being, you knew it was there but not where.
Probably it was just me being dumb but idk.
Does Linux turn you into a furry, or do you have to be a furry to use Linux?
I don't want to start a war here, but I don't get why people argue that the EU is better than the US because X or Z. We just side with who is the "less bad" and who action's directly affect us less or more according to our standards and reality.
This is just plain bullshit, at this point why they don't just convert their hidden dictatorships to real dictatorships? Let's censure everything, everything is bad, fuck that.
