After shutting down data access to several competing apps, Facebook today made two major clarifications to its Platform Policy, banning apps that use its data but don’t make it easy for users to share back to Facebook, or that replicate its core functionality without permission. Facebook Platform Head Justin Osofsky tried to calm fears by noting the majority of developers should “keep doing what you’re doing.”
The full-text of the revised section I.10 of its Platform Policy now reads:
Reciprocity and Replicating core functionality: (a) Reciprocity: Facebook Platform enables developers to build personalized, social experiences via the Graph API and related APIs. If you use any Facebook APIs to build personalized or social experiences, you must also enable people to easily share their experiences back with people on Facebook. (b) Replicating core functionality: You may not use Facebook Platform to promote, or to export user data to, a product or service that replicates a core Facebook product or service without our permission.
This replaces the former policy that read “Competing social networks: (a) You may not use Facebook Platform to export user data into a competing social network without our permission.”
