In the time since, I've found that advice to be so reliably true that it's one of the core things I use when deciding employers. A kind, pragmatic, ego-free CEO is mandatory for a culture that values the same. Likewise, the personality flaws in a CEO will propagate downward through the staff because everyone looks up to the CEO to signal what does and doesn't fly.
Anecdotally, I expect that Uber will not change while Travis is employed there, and as long as he makes more money than the lawsuits cost, (most of) his investors will find that perfectly agreeable.
