It does suck, but it has nothing to do with free speech...If they didn't allow you to post your options on your own site that would be a violation of free speech.
If you own the board, you have the right to allow whatever you want on it, just like we delete urls that lead to CP or lock threads of blatant spammers, but it doesn't block a person's right to free speech, however it allows us the right to operate a board the way we want to. So, if they want to delete negative posts, they have that right and you have the right to start your own board with whatever standards you want.
