The Electronic Frontier Foundation (EFF) has joined a global coalition of over 90 organizations to urge Apple CEO Tim Cook to stop the company's plans to implement a phone-scanning system. The system is intended to protect children and reduce the spread of child sexual abuse material, but the coalition is concerned it will weaken privacy and security on Apple devices. The EFF argues that the system opens the door to broader abuses and decreases privacy for all iCloud photo users. The coalition is asking Apple to abandon its surveillance plans and prioritize strong end-to-end encryption.
