You’d have to do a good bit of work to make Proton steam-free. No one is going to do that for 2% of the market. Just like arguing you could use Chromium and anyone who wants to make a browser can use it but realistically it creates an ecosystem around Google and for Proton, around Valve.
Don’t forget that the only reason Proton even exists is because they added a version of Steam Play to Linux Steam users.

Any other store can straight rip their compatibility tools if they want. It’s not their fault no one else can be bothered.
