I think it's mostly former apple users who like gnome (gnome 3 era anyway) the most, since to them MacOS looks awkward and slow.

Those users are shown too much in one go kde, lock up and scare themselves away from it.

KDE really needs to change how they introduce new users to it if they want to gain new users. The troubles this user had in KDE will actually help them do that in a small way, but they need more footage of first time users explaining what they are trying to do to help them see what's actually confusing of not obvious your first time around.
