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.
