One of the interesting aspects of large corporations is that different divisions can have goals which are very much at odds with each other. When AdSense sought to place its ads on as many publisher sites as possible, Anti-Spam had to figure out how to get MFA's out of the SERPs. AdWords wanted to maximize its revenues, and arbitrage helped with that but it ultimately threatened the long-term viability of AdSense such that AdSense is no longer willing to support that business model.
