Other bait-and-switch problems on Amazon are manufacturers and "brands" launching a product with high production standards, then switching them out with cheap, low-grade junk made with inferior components or materials later on. This is often coupled with rampant paid review scams, as discussed on HN (https://news.ycombinator.com/item?id=25459434 https://news.ycombinator.com/item?id=25459434) A twist on bait and switch is another manufacturer or reseller taking over the "buy box". This is how pirated items or used items sold as new get dumped on customers, with Amazon's full encouragement (lower prices for customers!) and non-enforcement/honor system for sellers.
