I use Linux at home exclusively (Linux Mint Debian Edition).

Don’t need Windows for anything but when I worked Enterprise IT the move to Windows 10 was a massive pain but we finally got it working and it wasn’t too bad as an OS. There is no reason why you’d want to upgrade.

As for home users, from my experience people don’t like change. If you move a single shortcut on the desktop , they are lost and panic .

So changing the entire look of the UI is not something people want. Plus Windows 10 auto update borked some windows 7 systems so users with that memory won’t be keen to repeat it by upgrading to 11.
