Gnome keeps making big changes that hurt users and app developers, at least in the short term. (Presumably in pursuit of the Gnome developers' vision.) If you do that often enough, users and app developers find themselves basically in a continual state of pain, always adapting to the latest change. But the Gnome developers either don't recognize this or don't care (or care more about other things), because they keep doing it. Thus: "My way or the highway".

I got tired of it, and the relentless dumbing-down of everything, and switched to KDE (in the form of Kubuntu). It's nice! And the developers seem to understand that it mostly works OK, and they don't need to force a UI paradigm shift on you (and their third-party app developers) every few years.
