What's interesting to me is that this is not a partnership between Twitter and Amazon. Amazon is simply using the API to get the hashtag results.

The way Twitter would want this to happen is by using Twitter Cards with a button to add to the cart. Of course they would be able to tax the use that way. I wouldn't be surprised if Twitter makes a move to block this functionality.

Honestly, this is great for Twitter. I can't see them blocking this. I can either advertise my product on Facebook which necessitates leaving the site in order to buy my product, or I can use Twitter Ads with #AmazonCart and see usage on a case-by-case basis all while staying within the confines of Twitter's app.

How could they block this? It's an incredibly general use case of their API.

Just block Amazon's servers.

Hahaha, yeah along with every service that runs on AWS? Yeah, don't think so.
