It has got to be discouraging to potential CEOs that Kalanick is still popular with employees and seems to want to come back.
And that he has control over the voting stock. He's quite far from a non-entity at Uber and quite far from Steve Jobs as Jobs couldn't technically veto his own firing.
Wow, I didn't think of either of those problems, but that would be a very rough position to occupy.
It's hard to imagine what alternatives the board has, now that the best candidates have all refused. Curious to see who else is in the running...
