KSO ads aren't served by ad networks, and Amazon prohibits ad networks from having access to the ads for the very fear you mentioned. The only data recorded are impressions and ad-specific aggregate usage -- how many times did people watch the movie trailer? How many people converted? There are no tracking cookies included with the ads. Amazon values its customers deeply and letting the third-party networks gather intel about its customers is a lose-lose proposition. Amazon loses its competitive advantage for having great data to make great recommendations, and customers lose their privacy. The ads don't work that way.
