I think it's more akin to multiple suppliers not multiple tenants.
1) There's a single unified storefront
2) Supplier of a product is transparent to the customer shopping experience
3) The checkout, payment, and shipping experience is singular and unified
The unified and efficient experience is amazon's strength, and I still make 90% of my purchases there. But yes, they should police and be held accountable for bad suppliers. It is amazon's store they are being sold at.
