And by "literally everyone", the usage of KDE is lower than GNOME because it is not the default in any mainstream dist with the exception of openSUSE. And if you're so into KDE you should be begging for the UX to improved instead of trying to pretend the way it is now is a virtue. It sucks. It sucks even compared to Windows. Because the KDE devs play the notes without understanding the tune. This has always been the case and makes for a complex desktop that generates support calls for admins who have better things to do.
I would say that maybe if the devs followed the KDE human interface guidelines they might improve, but the KDE human interface guidelines are practically non-existent, about 7 pages that read like somebody's weekend assignment. Spend the millions writing some proper ones, and adopting it. It doesn't require KDE become GNOME, but GNOME has at least made the effort and despite your dislike, it is an slick, unsurprising, simple, forgiving and discoverable desktop.
