Not with windows you can’t, which is the OS the overwhelmingly large majority of people want to use.
Most people don't replace SteamOS on their device so I don't think that's true. Plasma is a perfectly suitable replacement for Windows unless you really need access to Adobe products or something.
There’s more that work and work better on Windows than Linux than there are the other way around though.
True but It's a number that is shrinking every day. We are down to about ~100 games at this point that explicitly cannot work? I play a lot of games and I can't remember the last time I tried to play a game and it didn't work because I was on Linux.
I don't think there is any confusion about that
