Don't let EY chill your free speech -- this is supposed to be a community blog devoted to rationality... not a SIAI blog where comments are deleted whenever convenient.

You are compartmentalizing. What you should be asking yourself is whether the decision is correct (has better expected consequences than the available alternatives), not whether it conflicts with freedom of speech. That the decision conflicts with freedom of speech doesn't necessarily mean that it's incorrect, and if the correct decision conflicts with freedom of speech, or has you kill a thousand children (estimation of its correctness must of course take this consequence into account), it's still correct and should be taken.

(There is only one proper criterion to anyone's actions, goodness of consequences, and if any normally useful heuristic stays in the way, it has to be put down, not because one is opposed to that heuristic, but because in a given situation, it doesn't yield the correct decision. )

(This is a note about a problem in your argument, not an argument for correctness of EY's decision. My argument for correctness of EY's decision is here and here.)
