1. Very true
2. Wayland still has a lot of problems to iron out, and that's not something that will fly with most people as a Windows replacement.
3. KDE and Gnome are bloated messes that have 29394 ways of doing anything, but not everything, which causes frustration in new migrants. They don't want 12 different apps that each can do 70% of the possible options- they want one app that can do 100% (and isn't terminal). Familiarity with windows is also a plus to them, as a migrant.
4. Again, familiarity is a good thing for a migrant.

You're looking at it from the perspective of 'is this the distro that has things I want' which is, not to be rude, completely useless to the person actually migrating from windows.
