End of "Chat Control": EU Parliament Stops Mass Surveillance in Voting Thriller

The controversial mass surveillance of private messages in Europe is coming to an end. After the European Parliament had already rejected the indiscriminate and blanket Chat Control by US tech companies on 13 March, conservative forces attempted a democratically highly questionable maneuver yesterday to force a repeat vote to extend the law anyway.

However, in a true voting thriller today, the Parliament finally pulled the plug on this surveillance mania: With a razor-thin majority of just a single vote, the Parliament first rejected the automated assessment of unknown private photos and chat texts as “suspicious” or “unsuspicious”. In the subsequent final vote, the amended remaining proposal clearly failed to reach a majority.

This means: As of 4 April, the EU derogation will expire for good. US corporations like Meta, Google, and Microsoft must stop the indiscriminate scanning of the private chats of European citizens. The digital privacy of correspondence is restored!

The Myth of a Legal Vacuum

This does not create a legal vacuum—quite the opposite. Ending indiscriminate mass scanning clears the path for modern, effective child protection. Fearmongering that investigators will be “flying blind” is unwarranted: Recently, only 36% of suspicious activity reports from US companies originated from the surveillance of private messages anyway. Social media and cloud storage services are becoming increasingly relevant for investigations. Targeted telecommunications surveillance based on concrete suspicion and a judicial warrant remains fully permissible, as does the routine scanning of public posts and hosted files. User reporting also remains fully intact.

Digital freedom fighter and former Member of the European Parliament Patrick Breyer (Pirate Party) commented on today’s historic victory:

“This historic day brings tears of joy! The EU Parliament has buried Chat Control – a massive, hard-fought victory for the unprecedented resistance of civil society and citizens! The fact that a single vote tipped the scales against the extremely error-prone text and image search shows: Every single vote in Parliament and every call from concerned citizens counted!

We have stopped a broken and illegal system. Once our investigators are no longer drowning in a flood of false and long-known suspicion reports from the US, resources will finally be freed up to hunt down organized abuse rings in a targeted and covert manner. Trying to protect children with mass surveillance is like desperately trying to mop up the floor while leaving the faucet running. We must finally turn off the tap! This means genuine child protection through a paradigm shift: Providers must technically prevent cybergrooming from the outset through secure app design. Illegal material on the internet must be proactively tracked down and deleted directly at the source. That is what truly protects children.

But beware, we can only celebrate briefly today: They will try again. The negotiations for a permanent Chat Control regulation are continuing under high pressure, and soon the planned age verification for messengers threatens to end anonymous communication on the internet. The fight for digital freedom must go on!”

The Next Battle: The Return of Chat Control and Mandatory ID

Despite today’s victory, further procedural steps by EU governments cannot be completely ruled out. Most of all, the trilogue negotiations on a permanent child protection regulation (Chat Control 2.0) are continuing under severe time pressure. There, too, EU governments continue to insist on their demand for “voluntary” indiscriminate Chat Control.

Furthermore, the next massive threat to digital civil liberties is already on the agenda: Next up in the ongoing trilogue, lawmakers will negotiate whether messenger and chat services, as well as app stores, will be legally obliged to implement age verification. This would require users to provide ID documents or submit to facial scans, effectively making anonymous communication impossible and severely endangering vulnerable groups such as whistleblowers and persecuted individuals.

Background: What exactly expires on 3 April

An EU interim regulation (2021/1232), set to expire on 3 April, currently permits US corporations such as Meta to carry out indiscriminate mass scanning of private messages on a voluntary basis. Three types of chat control are authorised: scanning for already known images and videos (so-called hash scanning, which generates over 90% of reports); automated assessment of previously unknown images and videos; and automated analysis of text content in private chats.

The AI-based analysis of unknown images and texts is extremely error-prone. But the indiscriminate mass scanning for known material is also highly controversial, too: beyond the unreliability of the algorithms documented by researchers, these scans rely on opaque foreign databases rather than European criminal law. The algorithms are blind to context and lack of criminal intent (e.g. consensual sexting between teenagers). As a result, vast numbers of private but criminally irrelevant chats are exposed.

New Study Proves: Chat Control Software is Flawed

The fact that today’s decision by the EU Parliament was also technically imperative is proven by a newly published scientific study. Renowned IT security researchers analyzed the standard algorithm “PhotoDNA”, which is used by tech companies for Chat Control. Their damning verdict: The software is “unreliable”. The researchers proved that criminals can render illegal images invisible to the scanner through minimal alterations (e.g., adding a simple border), while harmless images can be easily manipulated so that innocent citizens are falsely reported to the police.

The Hard Facts: Why Chat Control Has Failed Spectacularly

The EU Commission’s 2025 evaluation report on Chat Control reads like an admission of complete failure:

**Data Giant Monopoly:**Roughly 99% of all chat reports to police in Europe come from a single US tech corporation: Meta. US companies acted as a private auxiliary police force—without effective European oversight.Massive Police Overload from Junk Data:The German Federal Criminal Police Office (BKA) reports that a staggering48% of the disclosed chats are criminally irrelevant. This flood of junk data ties up resources that are urgently needed for targeted investigations.**Criminalization of Minors:**According to crime statistics, around 40% of investigations in Germany target teenagers who thoughtlessly share images (e.g., consensual sexting).**An Obsolete Model Due to Encryption:Because providers are increasingly transitioning to end-to-end encryption for private messages, the number of chats reported to the police has already droppedby 50%**since 2022.**Failure in Child Protection:**According to the Commission’s report, there is no measurable correlation between the mass surveillance of private messages and actual convictions.

The Great Fact Check: Disinformation Narratives of Proponents

During the legislative process, foreign-funded lobby groups and authorities tried to pressure the Parliament through fearmongering. A comparison of their claims with reality:

Disinformation 1: “The European Parliament is to blame for the collapse of the trilogue negotiations.”(Claimed by the lobby alliance ECLAG and US tech companies)

**Fact:**It was the EU Council of Ministers that deliberately let the negotiations fail. Leaked Council cables reveal that EU member states showed no willingness to compromise, fearing that any concession could set a precedent for the permanent Chat Control 2.0 regulation. Parliament’s lead negotiator, Birgit Sippel, sharply criticized the Council:“With their lack of flexibility, Member States have deliberately accepted that the interim regulation will expire.”

**Disinformation 2: “Without indiscriminate Chat Control, law enforcement will be flyin
