Google's core business is advertising Google's core business is doing cool stuff with technology. While they often need to resort to advertising to monetize many of their cool products (see: search. What else could they do? The bar had already been set and a for-pay search vendor would be DOA), it does you no good to try to frame everything in the advertising picture. Amazon's core business is selling books. It would be sophistry to argue that AWS is really a mechanism to try to get you to buy books.
