Gnome2 should be forked and development continued by people with functioning brains.
Well, then: do it.
The ones currently developing are quite free to do the same: exactly what they want.
Or, you know, like someone who expects his software packages to be signed...
(And before you say anything, I don't think I have even been closed to an Arch package much less used the thing)
But choice does not mean that every piece of software has to provide you with every choice!
Gnome has decided where it wants to go. You may not like it, and you may surely choose to use something else which is moving in a direction you prefer. But Gnome is under absolutely no obligation to provide choices which go against what it thinks it should provide.
If you think the GPL is somehow related to all desktops environments providing all possible interaction option, you are seriously mistaken.
