Ubuntu is just a distribution. They don't directly hack on everything they ship. This is why they try to keep up with the upstream which releases the new versions. They do it in fact less than Fedora, which may or may not be a good thing. Maybe if they get really big they can afford to slow down.
To add my little Linux rant (as a stupid user):
I installed Ubuntu 12.04 and I had almost everything I needed after a 15 minute installation. I prepared mentally for a battle with Skype. It actually worked really well.
I toyed with gnome-language-selector and somehow my language got switched to Chinese. And then the 2 hour battle began. No matter what I did, my GNOME or Unity sessions stayed in Chinese. Ubuntu devs decided that I don't need to select the language at login, so I couldn't do it there, and the various locales didn't convince anyone except the shell that I don't want Chinese. Finally I opened again gnome-language-selector in which I couldn't previously select the language. Turns out I had drag and drop and not click the languages. So I had to pick up English and drop it above Chinese for it to work.
I should have reinstalled Ubuntu - it would cost me less time. And I still have no idea why I had Chinese in the first place.
