Amazon's not just an "open platform" here. Through deliberate features of their logistics system and customer-facing storefront, the primary branding on anything bought via Amazon is _Amazon's_. Take for example the FBA program with shared stocking. Amazon relies on a supplier's assertion that their goods are not counterfeit and are identical to others of the same SKU, but it then repeats that representation to the consumer on Amazon's own behalf. The advantage of Amazon's model is that it provides an integrated storefront, but it is not an "open platform" as a result. eBay is closer to an open platform, and there the difference between individual sellers is a first-order feature, where even sellers of identical goods manage their own listings and product descriptions.
