Amazon is getting aggressive at their SEO. Just recently, they introduced API calls limits for affiliates to 2500 per hour and up to 25K per hour based on your performance. However, the way it is structured, you have to be a large earning affiliate to hit that level. 99% of the affiliates will never see that level.
The effect of this is there are many affiliate sites out there using the API to generate entire websites that would in turn out rank Amazon itself. Now, that limit is going to kill those sites because of they are large, when the bots come crawling and get the limit error instead of the page, then they will eventually drop it from the SERPS and guess who moves up a notch for the item?
If I owned the Amazon site, I would own any and every listing I wanted because that site has such authority and it looks like Amazon has figured that out.
