>the Amazon app is highly likely to have people using their existing Amazon payment method. Let's say you want to sell your original product on Amazon, but you also have your own fulfillment center and a storefront on your website. What if Amazon removed you from their store, because your instruction manual included a URL to your website, and it was against the rules to tell your customers that you accepted payment outside of Amazon's ecosystem in any way. That's what Apple did with software, though suspiciously they left the largest, most litigious companies like Amazon alone, because they've been free to use their own payment systems for in-app purchases of physical products for years now.
