They control access to the customer. If you don’t think this is a valuable service, try selling stuff sometime. I sell on Amazon and they take 15% just for originating the sale, plus another 15% for FBA. If Amazon wasn’t around to charge me 30% to sell on their platform, I wouldn’t have a business.
