So as we know Windows Platform Apps and WinUI3 apps do not work on Linux, I keep wondering if Microsoft were to launch a new API let’s say direct X 15 but limit it to Windows Store Apps, and provided a way for the apps to be installed from other stores like steam could they in time kill modern Linux gaming.
This was why Valve invested in Linux and Proton. Microsoft talked about forbidding installation of Windows applications from outside their store under the guise of security.
