I'll take the charitable interpretation and assume you just don't understand the mechanics of the policy. Amazon is saying that sellers cannot offer a fair low price to customers on other platforms if the seller can't also offer it on Amazon. This is 1) anticompetitive, 2) anticonsumer, and 3) insane. Consider this test: - Seller buys a crappy LED bulb from China for $0.80 - Seller is happy to list the bulb on Walmar…
I disagree. Let's use your example. The sellers should stop selling that item on Amazon, and sell their light bulb on Walmart, or where-ever. Customers who really need that will go find it at Walmart, or where-ever. This strengthens the competitors to Amazon, which is bad for Amazon and good for the consumer. The consumer also find the lower price that they wanted. Alternatively, they buy the alternate product on Ama…
Online retailer Foo also has a store, and provide the same services that Amazon for their online shop at $5 per unit. The online retailer adds a profit of $2 per unit. Total price $17 per unit. Retailer Foo is more $ efficient for those services as a result customers price compare. Foo is rewarded for their effi with higher volume, manufacturer is rewarded with higher profit and consumer is rewarded with lower prices. Enforcing market competition led to all 3 parties involved being rewarded. Retailer Foo over time grows a larger customer base as people learn to price compare with them and forces Amazon to stop rent seeking.
But the above doesn't happen in the real world. Amazon enforces that the retailer lower their price on Amazon to $17, while still collecting $12 per unit. The company now can sell on foo, but only by selling on Amazon at a loss. They can't afford that amount of loss from Amazon and stay in business. So Amazon avoids competition. They can't pull their product from Amazon because not enough customers vist Foo retailer yet to make up the volume.
So in the end Foo retailer is more dollar efficient, but is prevented from growing and benefiting the marketplace. Amazon leverages its outside market size to avoid competition. Market participants preventing competition is against the benefits of capitalism and harms the consumer. So, it benefits the consumer to ensure Amazon has to actually compete with the more efficient competitor and stop rent selling behavior.
