Apple disabled its most secure data storage offering for new customers in the United Kingdom rather than comply with a secret government order.

In an unprecedented step, Apple caved to a reported U.K. government’s demand to prevent users from using end-to-end encryption in iCloud.

Earlier this month, over 100 cyber security experts, companies and civil society groups signed a letter calling for home secretary Yvette Cooper to drop demands for Apple to create a backdoor into its encrypted iCloud service.
