In January 2025, the UK Home Office issued a Technical Capability Notice under the Investigatory Powers Act demanding that Apple build a backdoor into its iCloud Advanced Data Protection (ADP)—an end-to-end encryption service protecting user files worldwide.
In reaction, Apple disabled ADP for UK users, stating that it “will never build a backdoor” and would instead withdraw the security feature entirely.
🏛 Legal & Privacy Response
Apple filed a legal challenge at the Investigatory Powers Tribunal, fighting to overturn the order. The court ruled the hearing must be public, rejecting the government’s bid for secrecy.
WhatsApp, alongside rights groups like Privacy International, Liberty, and others, have joined the case in support—warning that such a move could weaken encryption globally
Civil society organizations have also urged the UK government to revoke the order, citing risks to privacy and free expression.
🌏 International Fallout & Political Tensions
U.S. officials—including Vice President J.D. Vance—view the demand as a breach of the CLOUD Act and a threat to US–UK tech cooperation. The U.S. has raised serious objections, including potential infringements on free speech.
Under pressure, UK officials are reportedly seeking a way to back down from the demand, recognizing the diplomatic risks.
📉 Key Impacts on Users & Security
- UK users lose access to ADP, meaning new users cannot enable end-to-end protection for photos, notes, backups, and other data types.The Verge
- ADP remains active in other countries, shielding non-UK users with strong encryption.
- Security experts warn that any encryption backdoor—even if intended for law enforcement—introduces vulnerability for all users, including businesses and national institutions.
