Lennart's behavior in that talk does seem obnoxious, but the speaker also seems to be on-board with the adversarial banter, as well as there being acknowledgement of it being somewhat of a discussion-oriented format. Was that the way talks were playing out in general in that room?
I'm afraid that comes off like "If the speaker let it happen it's okay," which just rewards pushiness.
As I understand it, conference talks deliver their message first, THEN have a Q&A at the end where details can get sussed out or corrections issued. Lennart's time to complain or correct was after the talk.
I've been to talks where the format is deliberately more conversational. Lennart's raising that point when questioned specifically made me wonder if the room was already such an environment that day.
