I wouldn't really put a blame on the community manager.
They aren't really allowed to talk much about anything and they are most active in forum moderation, because well, its all they actually have the freedom of doing.
It does hurt to know a LOT and wanting to share it with players, but being chained down by NDA and higher ups.
Believe me, I live next door to gaming company, got 2 community managers in the house I live in, so I'm quite close to the subject.
