They don't let you use Gnome 2.x so in fact they are using the same strategy that Ubuntu is using: forcing users to use what they what them to use.
You also can easily switch to Gnome 3 on Ubuntu. At least there is a "classic mode" on Ubuntu.
Gnome guys were the ones that behave wrong here, with their pride, they changed a lot of things(in a wrong way) and did not let their users to vote giving them the option to use it.
E.g I need compiz cube, when you give a talk people watching need to know what you did with the screen. Every time I talked with devs about it they say that "you don't really need that, it is a flashy thing". Sorry I need it way more than "auto logging on IMs".
The new "cube equivalent" both on gnome and Unity crash on my computers.
