Do you think that's because he has experienced a genuine change of heart and intends on doing all in his power to repair at least some of his myriad grievous failures in the exercise of his responsibilities?
Or do you think it's because, this time, he's actually in the video, and really has no options beyond a) try to seem sincerely humbled and intent on improving, or b) do literally anything else, and look like such an unbelievably transparent asshole that no one will ever again take even slightly seriously anything he or his company tries to say or do to defuse the ongoing PR shitstorm, to say nothing of actively worsening said shitstorm?
I mean, don't get me wrong, I love that you're trying to give this guy the benefit of the doubt. I just don't see where there's any meaningful doubt left. Either he knows what's been happening on his watch, and he's so negligent in the discharge of his responsibilities that he's failed to avert a catastrophe - or he doesn't know what's been happening on his watch, and he's so arrantly incompetent that he's failed to recognize the possibility that, left unchecked, behavior like that apparently endemic within Uber would guarantee a catastrophe sooner or later. You seem to see some kind of tertium quid here, and I'd be delighted to hear you expand on that.
