The problem Facebook is always going to have is that courts are run by humans. And any judge is going to know Facebook's history. (i.e. the founders are now all billionaires off a stock sell that was "allegedly" fraudulent/misleading)
Also all the privacy issues they don't care about, the behind-the-curtain approach to customer support and their own legal issues (e.g. that the whole original Facebook code bit was "allegedly" stolen from Zucker's university).
Facebook walk into court every time with a big KICK ME sign stapled to their face.
