I still can't understand why Canonical doesn't just put out a Gubuntu similar to Kubuntu, Xubuntu etc. That way, they can keep pushing Unity forward while making it reasonably easy for uses who prefer Gnome to choose that option. I know it's possible to get gnome running (I did it on my netbook, which is running 11.10 - my desktop is still on 10.10), but the method feels unnecessarily hacky.

Because they guessed that not many users would switch to Unity if they can keep using a Gnome-2-like. But they _want_ them to switch to Unity so they have to basically force them by forcibly removing the Gnome-2 option.
I thought the idea of Unity was to attract new users with a simple interface optimized for non-power users. There's no reason why such an approach has to alienate existing users who like having a more expressive interface.
Because Gnome is breaking traditional Gnome workflows; Gnome 2.xx is only going to work for so long before dependency hell sets in; and Gnome 3 has some of the same problems for users as Unity.
