Apple has joined more than 80 technology experts and organizations in an appeal to UK lawmakers to consider the broader privacy ramifications of pending legislation called the Online Safety Bill.

The legislation, moving its way through Parliament, is intended to force accountability for technology platforms used to distribute child abuse materials.

Platforms like iMessage and WhatsApp use end-to-end encryption (E2EE), which prevents anyone but the sender and recipient from viewing the contents of a message. E2EE also keeps law enforcement from identifying illicit materials.
