what “many 3rd party companies” are you talking about?
When I switched to Mint about 6 months ago, most of my programs existed on both. And my games just worked. That wasn't the case just a few years ago.
Whereas EA are still actively blocking Proton in the BF6 beta?
I can't imagine wanting to give EA root access to your entire system, full access to everything you do on your computer...just to play a game. I'm honestly surprised Microsoft still allows such on their platform, it's a massive vulnerability to users, as CrowdStrike demonstrated.
