So I’m talking about playing previously Windows-only games on Linux, e.g. via proton.
I don’t know about the libraries etc that are used - is it possible for Microsoft to use some legal voodoo, for example, to suddenly end it all, and make the use of their libraries illegal (if they belong to Microsoft in the first place)?
Or could there be other ways of interference?
Eh, that would kill the steam deck though and then developers wouldn’t be testing their games out with it nearly as much. Sure proton would still exist in some capacity but it would be way shittier.
