Indeed, the "self censorship" described on wikipedia seems to have more to do with there being a pervasive threat of censorship and/or ostrasization from some governmental authority. One chooses to avoid taking the risk of official sanction voluntarily, but only because of the threatening environment. This is a form of censorship, in my opinion.

Changing the name of your web site as you see fit is the *exact* opposite of censorship -- it's free speech! Practically the definition of it.
