I think somewhere inside the complaint the point they were trying to make was that this website already had over 10,000 accounts and all of which are of Early Adopter status which makes that oh so 'rare' title, kinda pointless considering. Plus there's the fact that since people are given generous amount of invite codes, they can still hoard accounts and still invite everyone and their brother if they have 2-10 accounts or whatever.

Therefore, invite only = pointless. (in their opinion)
and EA = pointless (in their definition and opinion)
