I have a question about this, though. It seems like many of the top, successful tech companies were started by "brilliant jerks": Bill Gates, Steve Jobs, Jeff Bezos, Mark Zuckerberg, and Travis Kalanick were all known for being brash, arrogant, hard charging and willing to do things anyone with a decent sense of ethics would reject (e.g. Jobs swindling Wozniak out of his share of an early payment, Zuckerberg hacking into the private email accounts of Harvard Crimson reporters by searching Facebook's auth logs, etc.) These leaders also seemed to mellow as they and their companies aged, perhaps realizing what gets you on top is not what keeps you there.
Thus, I do hope Uber improves it's ways, but I also can't help but wonder if this very brashness that allowed Uber to develop such a toxic culture is also what let it (and other companies) beat out their competitors to begin with.
