This is what a PR tailspin looks like. All your good people will leave, all your bad people will have to be fired, and consumer demand and driver supply will be affected. Perception is reality, and that means Uber are in real trouble here and it's gonna cost them a lot – maybe most of the exec suite – to get out of it.
The key question is: who benefits? This is corporate politics by insurgent means, so I wonder who is emptying their opposition research briefing against Uber and why. Could even be an investor who wants to force leadership out, possibly as a prelude to driving Uber to an exit.
Those tactics don't work unless the dirt exists, so this really, really doesn't excuse anything which Uber may (and, on the balance of probabilities, there's more than likely fire to go with this smoke) have done. And I don't think it's likely the individuals alleging harassment in particular are part of this at all, so anyone coming trying to impugn their motivations can go pound sand; but, as a byproduct of their legit and serious grievances, they created the environment where this kind of power-play can be made.
So who benefits?
