Putting a bunch of APIs together in such a way as to create an entire copyrighted OS inside of another one 100% should be. You want to make DirectX itself for Linux, fine. But don't tell me you think putting it and a ton of other Windows libraries together -- even ones made "clean" -- to run an OS very closely to its target OS (and this isn't emulation, it's making your own version of an OS) is not a problem.

Like I said, making Wine and using it casually for a single person isn't the real issue here. It's concerning, yes, but when a single user is using it for their own purposes, I think there's nothing huge to be concerned with. When a major gaming corporation is using it as part of their own software running under a piece of their own hardware for financial gain -- really? You don't see the issue? How has Microsoft not seriously put an end to this already? If Microsoft is giving their blessing to this, they are opening up all sorts of copyright infringement across the board for software of all kinds.

Maybe if your mind is tainted by "Free software is holy and can never be wrong", you have this idea that it's fine. Free software is fine on its own as long as it follows a set of ethical and legal rules. Wine is definitely not doing this by allowing Valve to take their fork and making it part of their Switch-like hardware. Valve is specifically going full on Linux to avoid paying Microsoft for the rights to Windows on their machine, and using Wine/Proton to do this is simply wrong, no matter how you look at it.

I cannot believe anyone sees me as in the wrong on this issue. Valve should have pushed harder for native Linux gaming, but they failed, so they should have given up. Instead, they decided to do the wrong thing with something that should have been stopped from day one.
