They've already been well on this path. Every year or so they make a change to their API which always reduces what you can do with it. One year they removed much of the data people were using on their sites such as shipping costs and comments. Last year they removed your ability to access all the products in the Amazon marketplace (now you can only get the cheapest). They also constantly make the terms of service more restrictive. In the last update, they added wording that completely forbids use of Amazon associate links in websites or apps designed specifically for use on mobile devices (without written permission).
