I think your question is rather retorical, if someone makes information about themselves public, it's rather hard to just "take it back" once it's out there. I really can't see the Jehovah's Witnesses having any legs to stand on. From what I read, these quotes in question were not some secret memo that might have some protection under the law, although I don't know if religious secrets are protected in the same manner as trade secrets. In any case if the statements are made publically or in a publically available publication (hence the word Public-ation), they do not have any legs to stand on.
