I think it's more than "little motivation" if we're being honest. Right now Valve is quietly targeting MS' attempt to create a walled garden for gaming on Windows and (probably) cut them out. Their very clever approach has been a full end-run around the OS by using Proton, which I'm sure genuinely thrilled Apple... as long as Valve is only doing that to MS.
Why would Apple ever invite Valve to potentially do the same to them?
