If there is any truth to the Ceglia lawsuit, Zuckerberg really only ever owned 50% of FB. Ceglia claims he had a contract with Zuckerberg and funded the seed money for FB which gave him a 50% stake in FB. FB claims the lawsuit is bogus but I can't see DLA Piper representing Ceglia unless there was some credibility to his claim. Maybe Ceglia has a few million lying around to burn on a lawsuit though.
