Dunno, I’m absolutely sure there are some developers who were very rude to Jeremy, there’s a million developers who work on bitcoin in one way or another (though in context at Scaling Bitcoin it may not have been a relevant topic?). The discussion seems to heavily imply that all, most, or core developers are all rude or somehow stonewalling, which I find to be absurd.
I didn't pick up that implication at all from listening to the interview.
