I am surprised to see this on the front page of Hacker News. The article makes claims which are completely unsubstantiated. There is no audio/video evidence, and there is no other source (that I could find) corroborating the story, or even mentioning these phrases. From another comment here: https://twitter.com/alex_zee/status/1302284883625046016?s=21 IPC does not exist either.
Lack of formal organization does not imply lack of existence. Self-identification with a group creates grassroots organizations, with different characteristics than a top-down group, but equally existent.
