Amazon using shipping addresses in isolation to improve their business is not what people are concerned about here. It's perfectly legitimate for Amazon to say "we're getting a lot of orders from this list of zip codes, let's open some warehouses there". That doesn't infringe on anyone's individual privacy; the action is not tied directly to a single person, and especially not to further data collection/collation.
