It's a gamble, though. Say you're Uber's CEO, Travis Kalanick, and you believe 3 things for sure: 1. Uber's completely doomed if self-driving cars show up and Uber doesn't own it, 2. Sexual harassment is a good idea, and 3. Uber's behind the top players in self-driving car research.

Say you believe that there's a 25% chance that this Google guy can get you to the front of the self-driving car race, and there's a 50% chance you'll get caught. Based on those 3 assumptions at the top, this is a worthwhile risk.

Sure, he wouldn't do it again with hindsight, both because it didn't work out and because his board fired him for creating a culture of sexual harassment, but the risk was probably worth it, strategically if not ethically.
