Article 6(11) DMA Explained: Search Data, Contestability and Anonymisation
New Lecture added to my YouTube Channel!
Article 6(11) DMA is one of the most interesting stress tests in the EU digital rulebook. It recognises a real problem: if one gatekeeper benefits from behavioural feedback that improves search quality, rivals may need some access to that feedback for contestability to mean anything. But the implementation question is much harder than the bare provision suggests. Search data is not ordinary telemetry. It is semantic, contextual and often intimate. That is why the Commission risks creating a privacy fiction if it treats transformed record-level data, together with contractual restrictions, as though that combination automatically constitutes anonymisation. My lecture explains why the legal sequence must remain anonymisation first, utility second, and why the better answer is a Safe Search Data Access Regime rather than a one-size-fits-all dataset.
Q&A
Is this just a privacy veto over Article 6(11)?
No. The argument supports Article 6(11) as a serious tool for contestability. It does not say data should never be shared. It says that the legal condition of anonymisation must be satisfied first, and that useful access should then be preserved through tiered modalities.
Does your approach make the data useless?
Not if the architecture is properly designed. Head, torso and aggregate signals may support meaningful improvement. Some data can be exported. Some may require controlled access. Some may need suppression. The point is to avoid both unsafe utility and safe but meaningless access.
Why are contracts not enough?
Contracts can reduce misuse and define access conditions. They cannot alter the legal status of data that remains identifiable through realistic lawful means. A promise not to re-identify is not the same as anonymisation.
Are clean rooms part of the answer?
Yes, but only in a disciplined sense. A clean room is not a laundering device for non-anonymous data. It can add safeguards for data that has already met the anonymisation threshold but is unsuitable for ordinary download.
What does contestability mean here?
It means that rival search engines have a meaningful opportunity to improve quality and discipline the gatekeeper, not merely that they exist as formal alternatives. Search quality depends on feedback loops, and Article 6(11) targets part of that feedback infrastructure.
Why does this matter beyond Google?
Because the EU is already struggling with the meaning of personal data, pseudonymisation and anonymisation across the GDPR, the Digital Omnibus, DPA guidance, the DSA, the Data Act and AI governance. A weak DMA-specific standard would worsen that fragmentation.
