Two things stand out here: one, as you should know, crashes don't say anything about the UI design. At all. So let's move on.
Secondly, Linus's main gripe (and one of the most frequent complaints I've seen here) is that clicking on the terminal icon raises the current terminal, rather than creates a new window, and you now need to hit Ctrl-Shift-N for a new terminal window. Guess what? OS X does exactly the same thing: it raises your current terminal window, and you need to press Apple-N to get a new terminal window. Same goes for one of the other most frequent complaints I see here, namely Alt-Tab vs. Alt-` behaviour.
GNOME 3 is very different from GNOME 2, which I don't see them having made any apology for. This doesn't mean GNOME 2 has suddenly ceased to work somehow: you're more than welcome to keep running it if you think it's better.
I haven't seen any 'facts' in these discussions. I've seen a lot of people very upset that their desktop environment has changed, and very few actual facts. I also continue to posit that LWN commenters are a phenomenally poor representation of the average computer user.
