Apple has removed its strongest iCloud data protection for customers in the UK, as a refusal to comply with a government order demanding backdoor access to user data.

If a U.K. user has not already signed up for Advanced Data Protection, they will not be able to as of February 21, Apple said. Instead, those users will see a message: “Apple can no longer offer Advanced Data Protection (ADP) in the United Kingdom to new users.”

A secret UK order demanding that Apple backdoor its iCloud encryption appears to have prompted the company to pull Advanced Data Protection in the region.
