Allowing placing ads for one brand on another brand's terms supports a free and fair market, helps competition and promotes consumer choice. It means that companies need to continue to demonstrate to their customers that they are the right choice - because the customers regularly get to see what the competitor is offering. If a company worries so much about their customers leaving for the competition, perhaps it is because the company knows they aren't actually the best choice.

Playing devil's advocate for a minute here, I'm not sure how an advertiser bidding on a trademark or using a trademark in one's copy is "free and fair market". This current change is the equivalent of Circuit City running a Best Buy commercial and then sticking their phone number at the bottom of the screen.
