It's one of the downsides of being such a large company, some bad PR story is treated as if from one entity, because in people's minds Uber is just Uber. Having been on both the inside and outside when a horrifying news story comes out, I always try to err on the side of caution. It is near impossible as an outsider to know whether the problem is systemic or not. Interestingly, I'll bet it really slows down the amount of idealistic people who'd want to apply for a company though - I keep telling friends at amazon I'd be interested to apply but the risk of being put on one of the "bad teams" seems very high, and they've generally been in agreement because they agree it would be a risk - they read the same stories.
