Disagree. Speaking for myself, even if I already liked my leadership, if they gave me a mandatory 4 hour meeting with that kind of language, I would wonder if they had been eaten and replaced by aliens. Clearly something changed, because that's a bad meeting, and if I was ok with them before it's because they don't do stuff like that.
