That's implicit in ftse's point, which is to raise the question of when censorship is moral.

I'm sorry, it is not clearly implicit to me. I might have been too hung up on whether it should be legal or not.

I read his post and think: Yes, it can be legal for the company to censor their own website, and it would not be immoral for it to be legal. But, it would be completely immoral for them to remove a post from their website without fully dealing with the problem.
