This is almost intentionally obtuse at this point - and you're getting downvoted for good reason. You don't have a compelling argument here - step back, pause, and consider whether you're having an emotional reaction. Your argument is basically "Developers should do things I want, for my benefit, with no regards to the success or consequences of those actions". And that's a pretty fucked up argument. A much better argument is: Proton makes linux a compelling platform for gaming. There is a decent chunk of market segment that keeps Windows around only for gaming. Allowing those users to move entirely to linux increases the appeal of developing native gnu/linux games, because there is a much larger native market. This is how interfaces work - they allow you to develop new products that are compatible with the existing userbase. It's why they're incredibly important as stepping stones. --- Side note - Proton came out of codeweavers, codeweavers develop a custom version of Wine. Do you happen to know what Wine fucking stands for? hint: Wine Is Not an Emulator.
