I don’t see this nonsense in the B2B companies I cover. But there’s plenty of it in the social media startup industry, which has gone in a brief decade from revolutionary and democratic to — well, I was going to say “masturbatory,” but that insults wanking.
One of the reasons I don’t trust Facebook is that Mark Zuckerburg was a full-throated advocate of dudebro culture when he was starting out. I don’t think vast wealth and power are going to improve someone like that. They’re more likely to reinforce prejudices.
