> What Amazon is doing sounds more like stopping to be an open marketplace, depending on how hard it is to get approved. That's a solution, but at that point they are just another Target or Wal-Mart.

Good. If I buy from Amazon I want to buy from Amazon and Amazon alone. I'd never have considered buying Apple products via Amazon until Amazon recently became the exclusive seller of Apple products on their platform.

Don't get me wrong - I'm happy to buy from other reliable non-Amazon shops. However a seller that relies on Amazon or eBay but doesn't own/offer a trustworthy first-party store under their own domain, often feels cheap and like a someone willing to cut corners.
