I think what sets it apart in my mind is the "needed". In a Wikipedia article aiming to be authoritative and correct it may very well be "needed", but in a HN comment it is not "needed", it is "requested". Perhaps even "humbly requested". And the conflation of those 2 words tend to make the requester come off as judgmental/abrasive.
Everyone gets the reference, but it's not really the same situation.
