No I agree with you 100%. When AA sent me his first email stating that he was sitting on the bid with a huge order I was kind of upset about for the reason you stated. MM will make a market and that's what they did. That huge order was to tempting for MM and brought the price down to fill it.
I would of much rather seen that kind of ASK slapping at .0005 which could of turned into something nice. Folks see large buys on the ask and gives other investors confidence to slap the ask too. Also makes bid sitters think that the pps is slipping away from them and they start chasing.
