I'm not sure I agree that "most people don't care about the stuff you (as a Linux user) would care about". Some people put up with Windows problems because they don't know it could be different, to them that's just how computers work. Take automatic updates for example. More than once have I heard from a friend how they lost unsaved work or an overnight render because their PC rebooted for updates. While on Linux months long uptimes are the norm, and you can trust it won't reboot on you out of blue. Same with ads and other Windows annoyances.
Other people are bound to Windows by their software needs. You're right that many important programs are just not available on Linux (to your Office example I'd also add the Adobe suite). But the end user experience of Windows itself has been downright abysmal for a long time now, and for casual users who don't need much besides Chrome and a couple other Electron apps, modern Linux desktop might genuinely be the better choice.
