I agree the situation with Steam is not good on Windows. It’s already in a very privileged position because it can take full control of the screen with overlays, access controllers, and silently install games, all without the user ever seeing a single UAC prompt. I doubt those functional aspects will change in future. I’m glad the issues are getting more attention and hope Valve finds effective ways to harden their client. This is needed despite the walled garden they have.
