Nobody's getting screwed yet. Nobody had their data stolen then covered up either, until they did. No investors were lied right into their face about this either, until they were. No women were harassed and had the events covered up either, until they were.
If the company views engineers as better than other people and someone they wouldn't want to screw with, I'm not working there either on principle.
Google and Facebook are publicly traded companies and stock can be sold immediately; I'm not sure we can say Uber is not screwing employees until there is a liquidation event (not counting the internal buy back program)
