I joined Uber a few months before Travis left. I can share a few things that come to mind:
- shortly after Dara joined, he sent a company-wide email to the effect of "all corporate espionage projects must be halted effectively now"
- he introduced a new guiding motto: "We do the right thing. Period." and repeatedly refers back to it
- he found out about a previously undisclosed data leak and went ahead and made a proper public disclosure. The CSO had to leave the company and eventually got charged as a result[0]
- on an all-hands meeting centrally themed on making things better after the Fowler scandal fallout, a board member made a cringey sexist joke. He had to resign from the board that afternoon. This incident spoke volumes about how discrimination culture was no longer going to be tolerated.
- around the same time, as part of the HR revamp, a number of policies were introduced (training courses, anon hotline)
- there was a huge internal project called 180 days of change in response to the wave of scandals. This encompasses the safety features, along with improvements to the driver UX to make it easier to understand their income, among other things (which I hear were very well received by users).
