Wasn't the case in the beginning of the year and isn't the case at the end (I know people who have left this week for FANG). And that period arguably coincides with the most intense PR snafu for Uber. Most companies are smart enough to distinguish between a rotten top-mandated culture against individual actions, and not generalize 14k+ employees. Also worth noting that a large contingent were already former FANG employees so some are just returning back home.

With regards to why not move sooner, isn't the company going through an entirely top-down overhaul starting with the CEO? If someone wants to be part of that change, and if they still believe in the ride-sharing space and if they were never in the crossfires of any of this anyways, then all of these are valid reasons to stick around.
