I don't think I've ever seen a service that gets as much grief for making (usually positive) UX changes. It's easy to joke about, but even tiny things get spotted and people seem pretty hostile to the change.
On a computer or a cellphone I mostly can stick with (or downgrade to) "old versions" of the software if I do not like the UI - just as happened with MS Vista and now with Win8, or the Office 2003-2007 UI remodeling.
On a website, the only hope users have is massive outcries and shitstorming, even though its known that Facebook never listens to its users.
Also because the average Facebook user is not really computer literate, and such an user develops UI eidetic memory rather than functionality thinking - so moving a button leaves them clueless.
