Resistance against “Chat Control” grows — 500+ researchers warn EU

More than 500 researchers from 34 countries have signed an open letter urging EU governments to reject the proposed “Chat Control” regulation. They warn that the plan — which would require automated, suspicionless scanning of private messages, including end-to-end encrypted chats — is technically infeasible and threatens fundamental rights such as privacy and the confidentiality of communications.

Key points

• Signatories: 500+ cryptographers, security and privacy researchers from 34 countries.
• Main concerns: Technical infeasibility of scanning end-to-end encrypted communications without breaking encryption; creation of a mass-surveillance system; threat to privacy, data protection and freedom of expression.
• Political context: Germany is reported to oppose the proposal; the EU interior ministers are due to decide soon.

Why this matters

Mandating universal message scanning would weaken encryption and could introduce security vulnerabilities that affect all users. Researchers argue the proposed measures would be ineffective at reliably detecting abuse while exposing millions of lawful users to intrusive surveillance.
