Silicon Valley for the past five years has been afflicted by Wall Street ethics. I've seen this first hand at a few SV companies. As a male, I've actually faced reverse harassment. Never worked at Uber, but I'm speaking of much larger SV companies. HR is useless.
Silicon Valley is no different than any other place in the World. Just because people think they are "changing" the world doesn't mean ethics need to be on the line.
