This is a very common misunderstanding of censorship. Only the government can censor. If they kept Moore from filming, distributing, etc that is censorship. If Moore wants me to show the movie in my theater and I refuse, that is NOT censorship. That is me exercising my right to show what I want in my theater. I have the right to stand on public property and state my opinion (as long as I obey the law and don't cause a public nuisance). You have every right to refuse to listen to me. You also have every right to tell me I can't stand on your property and make a speech.
