I really hate this false dichotomy that gets perpetuated. No, being disruptive or innovative does not require being an asshole. And acting like an asshole does not make you more innovative or disruptive.
I hear statements like this all the time - "Well, {Jobs/Zuckerberg/Ellison/<insert figure here>} was an asshole." Being an asshole doesn't make you a better entrepreneur (and even if it did, is that really a pattern you'd want to perpetuate, or is it better to "disrupt" that too?)
Incidentally, Sarah Lacy (founder of PandoDaily) recently wrote a piece about this topic and used Uber as the main example[0]. Though even if she hadn't mentioned Uber, I think the point extends far beyond Uber, and she does too[1].
