Don't you see the contradiction in this? You want to make it possible to play
proprietary games "without... anything proprietary". That is literally
speaking impossible. If X is a subset of Y, you can't have X with no Y.
Note: I'm not aware of any libre games that use DirectX or the Windows API,
but if such games exist, they can be recompiled using Winelib and packaged
with the standard package manager, like the XM Solitaire example I mentioned
above. There is no need for anything like PlayOnLinux for any libre game.
What exactly do you think it means for there to be a libre version of
PlayOnLinux? Are you under the impression that PlayOnLinux itself is
proprietary? If so, you're wrong; PlayOnLinux is licensed under the GNU GPL.
You can check here for yourself:
The only thing non-libre is its listing of proprietary software (along with
parameters to run those programs correctly), but that information is the
entire point of PlayOnLinux's existence. Why would you want PlayOnLinux
without its most important feature?
