An open letter against Apple’s privacy-invasive content scanning technology

A large number of security and privacy experts, legal experts, and more, in an open letter to Apple:

On August 5th, 2021, Apple Inc. announced new technological measures meant to apply across virtually all of its devices under the umbrella of Expanded Protections for Children".

The open letter contains tons of arguments, scenarios, and examples from experts about just how bad this technology is, and just how easily it can be abused.
