GNOME 2 *upstream* is dead and GNOME 3 was that natural upgrade path for Fedora just like the upgrade from KDE 3 to KDE 4 or any other new upstream release. MATE and Cinnamon are more recent projects and they are available in the repo if you prefer them.
"You have responsibility to the Fedora community, and instead of admitting that the Gnome 3 shell UI is a point of pain for many in the Fedora community, you are in effect telling them to go away"
Now, you are being intentionally dishonest. I told you explicitly that I am working on integrating Enlightenment and I helped review Cinnamon as well. So no, I am not telling them to go away but use whatever they prefer and I am working on making those choices available.
