"Technical director Danilo Campos" was part of a major shitshow a year and a half ago on Hacker News (https://news.ycombinator.com/item?id=8389163). He called HN a cesspit and then tried to work up a Twitter mob against someone who made the mistake of challenging his points.

If a vindictive, narrow-minded individual like that is a technical director and a member of Github's social-impact team, no wonder people are leaving in droves.
