Recently, i had to move from nixos to windows against my will simpy because of anti cheats. While i dont game that much, the few games i enjoy playing are all online with some kind of anti cheat. I used to dual boot but i was tired of having to wait for my slow hdd to load windows (i only have one ssd). I literally used linux for everything else but because of anti cheats i am forced to move to windows. I managed to make it a little better by using wsl2 and removing bloatware but it will never be the same as linux
Which is fine, but it isn't a perfect strategy, because developers and publishers have complete control to replace the client at any time to add features you decline to use, and you are not automatically entitled to a refund if that happens.
Not every game on Steam has DRM. Lots will let you just copy your entire install directory to another machine and play without logging in to your account.
