There is!

I swapped a year ago, I went from Mint to Fedora then to Cachy. I use Debian on a home server and now NixOS on my laptop. I would say this is more of an issue with you and or the distro you chose aswell your hardware. In the last two months I even swapped my little brother to fedora cause all he does is game and all of the sudden I am not having to help him do anything or fix random errors, the only "hard" part or searching was nvidia and that was simple after reading one page of documentation. It all depends on what you choose, your desire to learn and your hardware. Also on Windows you have to go find the correct website and download the correct file from there, which is getting harder and harder with search engines feeding you the highest bidder instead of the actual site you need (This is how my bro used to get viruses because he didnt understand vetting websites)

You sound like an extremist brother. If they lie and dont do it (seems like they already have made it open-source) then get mad. But it sounds like you are upset because you got screwed by Sonos and Bose actually are attempting to do the right thing for their customers.

I use CachyOS on my main rig but i have a home server with debian i also use to game on every now and again, it was a great experience (besides nvidia drivers ngl) i dont understand why people try to scare others away from gaming with it
