Users are mostly afraid of wasting time trying Linux (any Linux) and having to go back to Windows for reason X, Y, or Z that they didn't even know about. For my partner who doesn't game, reason Z is one particular feature of Microsoft Word (the shrinkwrap application, not 365 Copilot App or whatever) that isn't emulated by LibreOffice or Google Docs. For competitive PC gamers, it's kernel anti-cheat. The Linux desktop story in general has been to slowly whittle down these reasons until there really is no good excuse for users not to switch and for vendors not to support the OS, even through compatibility layers.
