alt Hacker NewsThe article cites Amazon prohibiting sellers from selling their products for less on other platforms as anticompetitive behavior. I don’t doubt that this is happening, nor that it’s anticompetitive.
That being said, anyone who’s operated a two-sided marketplace knows that one of the biggest problems is consumers using your site as an index, and then seeking to dodge your fee by meeting with the seller on another platform, where they don’t have to pay it. This was a big problem for my startup.
This is a negative externality, because they’re extracting value from your platform (the list of sellers, products, prices, ratings, etc.), without paying for that value. If left unchecked, this could make running the platform financially unviable. One way to prevent this is to paywall your platform, but not every consumer wants to pay a subscription.
I think it’d be fair for Amazon to prohibit sellers advertising other platforms on its own, but prohibiting them from offering lower prices outside of Amazon outright definitely seems anticompetitive.

Sounds great to me!
The problem is this is all rent seeking and the leverage of moats like capital and network effects. It’s not actually valuable to society to defend. For a time it was new - now it’s not, and is just damaging fair competition. Amazon and other megacorp need to be taxed a lot more and broken up.

There is a company that operates an index where people can search for things and doesn't charge the site or the customer for things that rank well in organic search results. I think they're called Google. From what I understand they make quite a bit of money by selling ads next to the listings.
That model seems like it would work pretty well for such a platform, unless there was some major company preventing anyone from offering a lower price than they have on their own site so that everybody goes to their site instead of using a price search engine to find a site with a lower price.
I mean come on. If they're really using your site just to find a product, you think that's a problem?
Meanwhile a platform's fee should be going to things like payment processing, warehousing and shipping, and then if you're offering a competitive price for those services they should want to be paying you because they need those things and can't get a better deal on them somewhere else. If they can get a better deal on them and are only using your site because you're forcing them to with a dirty trick, maybe they're right to object?
