I've been running GNU/Linux only, no Windows, since 2012, and while there are one or two games in my library that don't work, I have nothing to complain about. Dragon's Dogma just works, Fallout New Vegas only needed DX9, Dark Souls 2 Scholar of the First Sin just works, Neverwinter Nights 2, X3: Albion Prelude, Baldur's Gate EE, BG2EE, Starbound, Devil May Cry 3, Oni, Homeworld,... so many games either just work or require clicking 4 times in Protontricks.

GNU/Linux has come far since I first started, my Radeon HD7770 first needed the proprietary garbage driver to run, which was a pain; but ever since it got supported in AMDGPU it was smooth sailing. I have an R7 card now and it also just works under AMDGPU. Meanwhile my roommate running Windows 11 had a bunch of pictures in her 'My Pictures' directory, got a message from MS saying 'oh, your OneDrive is nearly full', and when I removed the files from her OD, the bastards had the gall to remove them from her PC. Like, she has a 1TB SSD, why would you try to sync files on it to a 5GB cloud storage? And then she naively said 'oh, maybe I should just pay to get more storage', and I flipped my lid.

So yeah, 'a couple of games don't really work' is not a very convincing argument compared to the anti-user hostility MS exhibits in my opinion. But then, I could be wrong.
