EU Rules Would Require Tech Firms to Tell Companies How They Rank Products

Google, Amazon and other tech firms will have to tell companies how they rank their own or rival products on their platforms under new rules agreed by EU negotiators aimed at stopping unfair practices by online platforms and app stores. Proposed by the European Commission in April last year, the platform-to-business (P2B) law is targeted at Google Play, Apple App Store, Microsoft Store, Amazon Marketplace, eBay and Fnac Marketplace.
