It would be quite interesting to know how this data is actually used on Amazon's servers. It reminds me of the criticisms of government data collection programs, that they just hoover up every bit of data that's available without actually knowing what to do with it. Suppose you train some AI to predict what pages in a book will be most engaging to the reader. Since your interface to the book is still just going to be something where people can turn the pages what are you actually going to do with that information? It's a massive sacrifice of the privacy of the user for small gains at best in getting insight into the user's behavior. I wouldn't be surprised if this information is sitting in a database somewhere at Amazon completely unused.

The philosophy of Amazon appears to be to do as much as possible in the hopes that one day it will be useful. This is at odds with the principle of philosophical skepticism, that because we can't be sure of the consequences of our actions we should strive to do as little as possible. The data could be hacked and leak out, for example. There is tremendous uncertainty around things like that.
