That was an executive who Kalanick fired because of what they did.
They were fired three years after "what they did," and they included Kalanick in the original communications so it seems more that they were fired upon being publicly caught.
Said executive(not Travis) didn't publicly call her a liar. He proposed a theory in private and so that they could do some fact checking. That's called not being played for a fool
Pulling a medical file as part of the fact check was a gross violation of privacy however.
Neither. In the end money wins.
They're pot and kettle. I don't think it matters much in the long run who the soot lands on.
