Former Twitter CEO Jack Dorsey questions Apple's exclusion of bitcoin support in its mobile payment service, Apple Pay. This comes after Apple warned Bitcoin-friendly social media app Damus of possible removal from the App Store for violating the platform's terms of service. Damus allows tips using bitcoin, whereas Apple Pay does not support crypto. Integration of bitcoin into Apple Pay could significantly boost mass adoption of the cryptocurrency. The situation highlights Apple's power over consumer applications and raises questions regarding the need for a resistant financial system. Apple CEO Tim Cook has not responded to Dorsey's inquiries.
