There are lots of games that run on linux these days. Personally, my wishlist has a deep enough backlog of linux-supporting games that there's very little risk I'll ever be "forced" to dip into the windows-only portion of the list.

For those times when I really just want to play a specific game that's Windows-only, dual-boot works great. I couldn't care less if telemetry tells Microsoft I start my PC every few months to play a few games ;)

I'm pretty skeptical that there are many real cases where eliminating Windows as a primary OS is a matter of "can't" and not "don't care enough to tolerate an occasional minor inconvenience". The latter case gets little sympathy when they complain about Microsoft's bad behavior.
