The Signal Foundation announced on October 3, 2025, that it would withdraw its encrypted messaging service from Germany and potentially all of Europe if the European Union’s Chat Control proposal passes in an upcoming vote. According to Signal President Meredith Whittaker, the messaging platform faces an existential choice between compromising its encryption integrity and leaving European markets entirely.
The German government holds a decisive position in the October 14, 2025 vote on the Chat Control regulation, which aims to combat child sexual abuse material but requires mass scanning of every message, photo, and video on users’ devices.

The Chat Control proposal mandates that messaging services like Signal, WhatsApp, Telegram, and Threema scan files on smartphones and end devices without suspicion to detect child sexual abuse material. This scanning would occur before encryption, according to technical documentation from the European Commission’s September 2020 draft on detecting such content in end-to-end encrypted communications.

The Chat Control vote reveals deep divisions among EU member states on digital privacy and surveillance. Fifteen countries support the proposal, eight oppose it, and several remain undecided as the October 14 deadline approaches.

Germany’s position remains critical and undecided. Despite expressing concerns about breaking end-to-end encryption at a September 12 Law Enforcement Working Party meeting, the government refrained from taking a definitive stance. This indecision makes Germany’s vote potentially decisive for the proposal’s fate.
Belgium, Italy, and Latvia remain undecided as of September 23, 2025. These countries express desire to reach agreement given the expiring interim regulation, with all three expressing support for the proposal’s goals while remaining formally uncommitted. Italy specifically voices doubts concerning inclusion of new child sexual abuse material in the scope of application. Latvia assesses the text positively but faces uncertainty about political support.
Poland and Austria share the desire for solutions but maintain skepticism about the current proposal’s approach. Greece’s position remains unclear, with the government evaluating technical implementation details. Sweden continues examining the compromise text and working on a position. Slovakia appears in both opposition and undecided categories depending on sources, reflecting the fluid nature of negotiations.
The arithmetic suggests that Germany’s decision could determine whether the required majority materializes. With 15 states supporting and 8 opposing, the undecided nations hold the balance.

Technical experts have warned that client-side scanning fundamentally undermines encryption security. A comprehensive 2021 study titled “Bugs in Our Pockets: The Risks of Client-Side Scanning,” authored by 14 security researchers including cryptography pioneers Whitfield Diffie and Ronald Rivest, concluded that such systems create serious security and privacy risks for all society.
The researchers explained that scanning every message—whether performed before or after encryption—negates the premise of end-to-end encryption. Instead of breaking Signal’s encryption protocol directly, hostile actors would only need to exploit access granted to the scanning system itself. Intelligence agencies have acknowledged this threat would prove catastrophic for national security, according to the technical consensus outlined in the research paper.

Germany’s historical experience with mass surveillance through the Stasi secret police informs current privacy advocacy. The country maintained principled opposition to Chat Control during the previous coalition government, though this position became uncertain after the current government took office

Denmark assumed the EU Council Presidency on July 1, 2025, and immediately reintroduced Chat Control as a legislative priority. Lawmakers targeted the October 14 adoption date if member states reach consensus. France, which previously opposed the measure, shifted to support the proposal by July 28, 2025, creating momentum for the 15 member states now backing the regulation.
