This is a chicken egg problem, where distros claim they want more users, but when they get users complaining about usability problems, users either get ignored, get ridiculed, or are told it works by design they should adapt.
So until there are just enough of a certain kind of user who can adapt, but still complain and insist on software becoming more usable, things can change.
And face it, both macOS and Windows have had persistent crappy UI/Ux of their own, it's just not as such a critical mass that people say f it, I'm going back to pencil and paper (which when it comes to proprietary voting systems, we should sooner be on pencil and paper).
You're missing the point. It isn't about "bad" UX, but consistent UX that omits implementation details. With the exception of Win8, both osx and windows have huge consistency points.
