Beside the fact that they lied to Congress about.. I guess there is an expectation. If you put your products on Amazon marketplace, you are expected to join a marketplace. You don't necessarily expect for Amazon to also join the marketplace by using your data to compete against you. Also you can use Amazon services and warehouses even for products that you do not wish to sell on Amazon website. Essentially using Amazon as a 3PL service. Again, you might not expect Amazon to use your data for their own products. If you sell your products to Target, this isn't exactly a marketplace. This is a retail outlet. You know they can measure your sales, measure your competitor sales, etc. And you know they won't lie to you about doing it.
