I think self-censorship is somewhat of a misleading term. Self-control is central to human psychology, but it is different from the idea of censorship where one party prevents the voice of another to be heard because it is against the interests of the former. I certainly agree that this video is not prudent, and hence will not achieve anything. It is quite another question whether this means a company like Google should judge this and take action on it without a court order. The reason to call this censorship is because the decision not to distribute is probably politically motivated. Compared to the examples you cite, this video is very much relevant to public interests, i.e., people will want to know what all the fuss is about. This does not hold for your examples of 'hobo fights' and nipples.
