google bans competing text ad networks, folks (Score 1)

their TOS states that if you're in the adsense program that you can't use adbrite, or yahoo publishing, or MSN's ad program, or in fact ANY OTHER TEXT AD NETWORK. so where's the outcry over that abuse of monopoly power? is it OK for google to tell people using its service that they can't use a competitors ad program, but its not OK for ebay to say you can't use a competitor's payment program?
