Decentralized social media app Damus says Apple rejected an app update and asked it to either remove its tipping feature or use Apple’s in-app purchase system  —  Damus, a decentralized social networking app backed by Twitter co-founder Jack Dorsey, will be removed from the App Store due to Apple’s strict payment rules.
