Valve has the resources to hack Proton to make things work, others just want an OS they know will already run Windows games without much fuss. Valve specifically wants to move away from Windows because of fears of anticompetitive behavior from Microsoft. They’re not just doing it from the goodness of their hearts. Microsoft would like nothing more than the Steam store crushed and all its games moved to their own walled garden.

Lenovo has fucktons of resources to do this sort of thing. Probably more than Valve!
Not only that but I guarantee that Lenovo probably has 10x more Linux engineers and developers than Valve working for them full-time, right now.
