Windows has always been free for me so it’s no big issue. But yes, as a current Windows 10 user my point still stands that the best of both worlds is using it IMO. Have the widest support for games and can easily remove any bloatware you want from it already.
You are the one who originally changed the goal posts about it being changed in 2 years time and that being an issue. I’ll worry about that in 2 years time - for all we know Microsoft will extend the support.
But also to your point, Linux is very young itself so you can’t expect it to always be around. Once it’s around for 100+ years sure, but I just don’t see that being a thing. There’ll come a time where it’s no longer relevant.
