> No, because Shopify doesn't compete against its own sellers. The antitrust concern arises solely because Amazon is both the platform and a competitor and it uses its access as the platform provider to acquire data to compete. One can always make the argument then, that just use Shopify and don't come to Amazon. Amazon can even make the case for Google and FB having sufficiently big audience size for customer acquisition. Unlike an app which needs to go through AppStore to end up on an iPhone, a product being sold on Amazon doesn't need to go through them for customers to purchase it. > Yes, they are. They use this data to determine what products (specifically, what SKUs) to re-order from their suppliers. So does Amazon, but both don't limit themselves to just this use case.
