Suelette Drefus, Julian Burnside, Kristinn Hrajnsson, and Lizzie O'Shea were the main people in this event. I have transcribed some of Suelette Drefus, Technology Researcher and Author's excellent summary of Julian Assange's contributions to the public internet and free software. She also displayed courage in criticising powerful people on stage. At around 1h 44m into the video she has the courage to criticise corporate media journalist, Peter Grest, for his repetition of opinions used to slur Julian's credentials as a journalist and publisher. Interesting to wonder why Grest was released without explanation after an international outcry from the same western block that is either persecuting Assange or leaving him to rot.
The film of the event is now on twitter broadcasts. The introduction to the main speakers starts around 17.40 minutes:https://twitter.com/i/broadcasts/1YqKDnymbLwJV?fbclid=IwAR2MhE7PGdDm6ZN0lbSn25y5AdS9QQftWBsJZ_uOpZUDua_3WZPRb5bi74c
