I disagree with your point, but understand it.  People who paid with BTC (assuming they get their units before the difficulty goes through the roof) will probably have more BTC afterward.  However, they would have even more BTC had they done something else, such as if they had sold BTC at $250 and then bought it back at even where it is, $90 (actually $94 just checked).

And if, as most people even those who use BTC, they denominated their net worth in some other currency, like USD, they spent BTC on their pre-orders at USD values back when BTC was worth much less, and had they not even made a purchase, but simply sat on their BTC, they'd already have made a huge profit.  So buying a pre-order was a huge mistake.  It was based on the notion that BFL was going to deliver product with vastly greater specs than anyone else was able to deliver.  It was coming any day now.  So stay away from Avalon and anyone else (those who are actually delivering reliably).

That's really where the scam part comes in.
