I follow the tech news a bit more than the average person (but perhaps about average for the HN crowd), and my opinion of his leadership really couldn't be lower. Perhaps it's lower than Uber itself though as well because while I have little to no respect for the Uber culture, I generally agree that actions like theirs in the rideshare space, despite being heavy handed and pushy, spur innovation and put regulators on the defensive, which in turn forces regulators to adapt faster than they normally would--like a forest fire can lead to a stronger ecosystem.
