"it is not a stupid person ... It is a person who almost certainly has no indication that he will suffer any negative consequences"

Jackets and sexual advances are likely just the symptoms. From Fowler's account it sounds like root cause is a political culture where individuals (esp management) are incentivized to act in their own self interest. Any employee can safely ignore another if that other employee is not politically tied to their personal advancement.

I'd like to think this is the wrong side of history, and that smart people should put their self-worth in acting in ways that optimize the benefit for all stakeholders. However, many political science theories predict just the opposite in large political organizations where selfish actors aggregating power end up at the top.

I know very little about Uber's org, but a leader with a Machiavellian hat on would likely focus on hiring management that are adept at acting politically. A political culture will eventually weed out those who are not.
