OK that is not really what I would call censorship. Censorship is restricting public access to some expression - not punishing the originator. Even if it might be just as bad for the freedom of speech, it is not the same thing.

If the effect is to stifle the speech then functionally how is it different?

[olavk]

Quite different actually. (Even if two things are both bad it does not mean they are the same thing!) For example you can censor a dead author, but you cannot threaten him. And you can punish someone for saying something without censoring the utterance.
