The Duff CEO with a Windows-Logo on his forehead: "Gamers use Windows because of its' user experience not our de facto monopoly."

Edit: Yo, I'm not saying this is gonna happen. I just want to say that Windew's UX sucks ass.
This is the main problem right now.
People want to return to a lighter simple Windows OS, but Microsoft is making that increasingly hard to access. The LTSC version of Windows 10 is close(No AI, No Ads, and minimal telemetry that can be disabled), but they dont sell it to the public unless you buy 5 copies, and ~~there is no LTSC version of Windows 11 yet.~~ looks like they finally released it a couple months back, but people are unhappy with it.
Linux offers an alternative, but compatibility is still a huge issue despite the impressive gains Wine and Proton have made in the last few years.
The reality is that if you have a Windows PC you can basically guarantee that you can install anything you might want(barring hardware limitations). You can often make that software work on Linux too, but there is always some tinkering involved and the general public doesn't want to deal with that, nor do they want to change to a FOSS alternative.
And if you like playing certain games with kernel anti-cheat, the only way you're getting away from Windows is on console. Unless gamers jumping from Windows to Max/Linux increase by improbable orders of magnitude, that's not changing anytime soon.
