Can you provide more context re: "The recent reaction from Valve is telling, I think Gabe is fearful about the current state of affairs" ?

I think it's a reference to steam proton, a compatibility layer they built to run windows games on linux.

Microsoft could lock out 3rd party app stores like Steam, and already has on certain versions of Windows.

Valve is trying to protect themselves from irrelevancy, they have all their eggs in the Windows basket, while consoles and mobile are owned by companies that are massive comparatively.
