There is something of a personality cult around him, to which I don't subscribe. (I distrust personality cults.) From what I've heard (I've never met him) he doesn't seem like a pleasent person to be around. To me this is not especially controversial, as he's basically a CEO. I expect CEOs to be SOBs. I honestly don't know that the event could be held in its current form without having someone of that sort in charge. The logistics are too big.
Of course, I could just be a brainwashed knee-jerk apologist flunky, seduced by the aura of power around him, so do some poking around and come up with your own conclusions.
