"They can't run their applications on Linux or MacOS (or they certainly would)"
The vast majority of Windows users do not use Windows-only applications. They're using a browser, probably an office suit; both can be done on macOS or even Linux just as well.

Ironically, the buying-because-of-lock-in argument most describes macOS and especially iOS.
