Most people (at least in my experience, you know, the one who's making the subjective judgement about him being a dick) can be angry without saying something pretentiously mean like that.
It's ok for the conclusion here to be, "Rick's an asshole who should've been fired but management fucked up pretty badly." Situations don't have to be binary with only one party at fault.
EDIT: Let's also not forget the accounts of Rick supposedly berating people in meetings. If multiple people think you're being mean to them, you're probably being mean.
