I have hundreds of books, partially due to how good Amazon's book recommendations used to be. They are now mostly paid ads as well, and are of much lower quality. It definitely feels like a very un-Amazon thing to do, unless the lens you look at it through is "Customers really care most about price and charging sellers for ads lets us lower prices", but that feels like a stretch?
