This is a hilarious comparison because it really feels that way. Why would you as a company need to defend yourself of accusations like this if they aren't true? Why not sue WSJ for libel? It's not like Facebook doesn't have the cash to do so. Oh wait, that would mean that they have to prove damages and have the spotlight shown further. So they don't do it.

Responding to the allegations is almost worse than remaining silent. It shows they are aware it's a problem and the government stepping in is the only way it'll stop.
