I don't think UX is controversial, if you look at it from the perspective of average person. I was annoyed time to time by changes in Gnome UI. But I would not say I find KDE, XFce, Windows 11, Mac... more productive. I switched my old man from Windows to Gnome and had zero complains (which is rare). Having Gnome default makes sense as switching will not be a problem for advanced users. I personally don't have reason to switch.
