Movies were not suppressed by government edict (at least in some communist countries), the way those coffin photos were. (I dare you to invent an argument that that was not censorship, either! ) Decision not to distribute was also 'business decision': after a phone call from 'high places' the boss of production company would decide it was not such a sound business idea to distribute the film that displeased the guy on other end of the line (who would, of course, explain that the audience would be offended by the film); if he did, the company would not get subvention next year, and the boss' chances to be elected in Central Comitee would be greatly diminished. Of course, these consequences were implied, never explicated. I fail to see any fundamental difference. If Disney really thought the profile of Moore's work does not fit expectation of their audience, they would not finance it in the first place.

As for Moore's feelings about Disney's decision, I will join cynics in claiming this plays into Moore's hand (is that an appropriate idiom?).
