Web has become the default platform, where most people run most of their app/spend most of their time. Even Microsoft has had no choice but to embrace it, and Outlook (as in, the one from Microsoft office) is now a web first app (normal outlook is rebranded "classic" and we all know where this is heading, for better or worse). In a way, that makes switching OS much easier.

If you add to that that Windows itself is getting major visual overhauls from version to version (sometimes even within) it's not like sticking with it protects you from having to learn different UX paradigms and habits.

And regarding gaming, well, linux with Proton runs games faster than Windows nowadays, that's how little Microsoft cares about gamers/how good Valve is (depending on how you look at it), but the fact of the matter remains.
