When you really lose trust from your partners because officially announced things Amazon does, like adding your products to their shop system, then your partners have no trust in you at all.
When you don't want that Amazon sells your products, cancel the orders you get from them. Add a link to the real shop and a explaination why to the cancel mail.
It could all be so easy. And this are just the things everyone could do. Delivering doubled prices to AI crawlers would be a advanced thing.
