Fireship - UK demands backdoor for encrypted Apple user data...
The UK government has issued a technical capability notice to Apple, demanding the creation of a backdoor to access users' encrypted iCloud data globally. This demand is part of the UK's broader surveillance efforts under the Investigatory Powers Act of 2016, which grants extensive data access capabilities to intelligence agencies. The notice is controversial because it challenges the privacy protections offered by Apple's Advanced Data Protection service, which uses end-to-end encryption, meaning only users have the keys to their data. The UK government's demand is seen as a threat to global privacy, as it could set a precedent for other countries to follow. Apple has historically resisted such demands, as seen in their refusal to unlock an iPhone for the FBI in 2016. The video suggests that Apple might negotiate a compromise, potentially discontinuing the service in the UK. For users concerned about privacy, the video recommends using end-to-end encrypted apps, full disk encryption, VPNs, and the Tor browser to protect their data.
