The blog by Susan J. Fowler (former engineer at Uber who has written at length about the toxic and illegal HR activities at the company) reveals who dysfunctional that company was - and likely still is.

Reading those stories is shocking...but then, not really.  Think about it: Uber's entire business model is being this monopoly of data and control - ie, a massive pyramid scheme.

That mindset, esp to push up the stock, is going to cultivate raw aggression in upper mgmt that sets the tone for whole company culture = sociopaths thrive.  By comparison, odds lower this happens at Tesla
