Pax Dickinson has been forced to resign as chief technology officer at Business Insider following an online firestorm over his long history of controversial tweets, according to a source who has been in contact with him. Dickinson got in hot water yesterday over his most recent string of tweets about feminism, misogyny, and women in tech.

An e-mail seeking comment from Dickinson was not immediately returned.
