The relevant detail is that you can indeed censor a publication by adding a rule that says "you can't censor your publication in the following ways". I don't personally use Facebook at least in part because I don't want to use a centralized, censored system, but the fact of the matter is that it's a bad idea (not to mention likely an unconstitutional one) to tell Facebook what they cannot publish and indeed what they must publish. Although it's irrelevant to the point, I also don't totally understand the nature of your objection. If you are saying that any publication gets to define what it does and does not publish (i.e. Facebook says "I am a company that publishes non-nude photos" or "I am a company that publishes censored material"), then they merely have to re-define their service in order to censor people while complying with whatever scheme you have in mind.
