This is tailored to people in inefficient VC-istan companies where engineers don't get to speak for themselves, hence "involve engineering management". Ok, we're done here.
I agree that there are a lot of terrible, arrogant PM's out there. PM is the ultimate MacLeod Clueless job in many organizations (with engineers closer to the MacLeod Loser tier) because it involves a lot of context-switching and annoying work, but is ultimately just as subordinate as anything else, since the job still involves serving executives.
