I've met him, and I worked with him 4 years ago. This is a man who, if he'd kept his mouth shut, could have worked anywhere, climbed up the ranks quickly. Unfortunately, he has an OCD focus on social justice, and was willing to risk his career for what he believed in, and he's been made into a villain figure for some reason, just because he said something harsh about Marissa Mayer and didn't like his experience at Google.
Since then, he's been attacked from all sides and a number of people have tried to erase him. I don't know if YC was behind the Quora ban (I actually like Y Combinator) but it's obvious that something fucked up happened.
Is he a bit arrogant? Sure, although less so in person. Does he cultivate an obnoxious internet personality? Yeah, to some degree. But he's also insightful and, unlike most people who just care about making money, he actually cares about the direction that our industry is taking.
Am I the only one who sees this?
