My theory is that Jack is trying to expose the flaws of twitter to the rest of the company. A way of bludgeoning the stubborn in the company by a blitz of bad press
His recent interviews and (lack of) leadership have shown that he bludgeons no one, and the stubborn person is him. He's just an unusual kind of stubborn: unwilling to make any decision at all.
He also refuses to let inside forces impose order on it. He doesn't do anything at all. I would call Twitter a camel -- a horse designed by committee -- but it seems it's not even that. He apparently just consults committees ad infinitum and then does nothing.
