I did read it; I'll add color to my reply and hope it makes more sense to you. Adwords auction favors the most aggressive marketers some who's successful strategies are considered scams by me and other folks (but maybe not by google for now). What aggressive marketers are doing that allows them to bid the highest price may not be against google's terms of service (or illegal), but those strategies maybe considered unethical by other marketers that then won't compete with the bids. That's why I said google's auction creates an incentive (favors) the most agressive marketers (with the most scammy strategies) to win. That's the logic.
