Having once worked for Intel, that seems about normal for vital information to pass from one fiefdom to another. The poor sap manning the forum wasn't saying "we're not telling you", he was saying "they're not telling me".
(Now, if the other guy thinks you're encroaching on his turf, the response time approaches infinity. In that case pretending to be a member of the public on a forum might be an effective strategy; if I'd listened to Andy and thought of it myself I might still be there.)
