UK MP Chi Onwurah proposes digital twin regulation for streaming platforms

The immediate implication is a potential shift in how streaming services deploy recommendation engines, as the bill challenges the legality of using behavioral replicas to drive engagement. For the broader ecosystem, this signals a move toward 'data sovereignty' where platforms can no longer treat user preference models as proprietary assets without explicit consent. If passed, this could force a technical overhaul of personalization stacks to ensure they do not cross into 'digital twinning' territory. Industry observers should watch for the House of Commons vote on Wednesday to see if the bill gains the momentum needed for a formal first reading.

Chi Onwurah's push to regulate digital twins arrives amid a broader wave of UK legislative activity targeting algorithmic systems. The UK's Online Safety Act, which received Royal Assent in October 2023, already imposes duties on platforms to assess risks to children from algorithmic recommendations, and Ofcom published its first set of children's safety codes in July 2025 requiring platforms to conduct impact assessments on recommendation systems that could expose minors to harmful content. Onwurah's bill would extend that logic by targeting the underlying user models themselves, not just the outputs. The Information Commissioner's Office has also signaled interest in profiling practices, with ICO guidance updated in March 2025 clarifying that automated decision-making under UK GDPR Article 22 applies to recommendation engines that significantly affect users, creating a potential legal foundation for Onwurah's digital twin framework.

The business implications for streaming platforms are significant given the centrality of personalization to retention economics. Netflix disclosed in its 2024 annual report that its recommendation system drives approximately 80% of content watched on the platform, and the company invested over $1 billion in personalization and content-matching technology between 2022 and 2024. Similar reliance exists at Disney+, where Bob Iger told investors on the February 2025 earnings call that algorithmic curation was a top priority for reducing churn. If Onwurah's bill advances beyond a Ten-Minute Rule debate, platforms operating in the UK would need to demonstrate that their user preference models do not constitute exploitative digital twins, a standard that could require consent mechanisms layered on top of existing terms of service.

On the technical side, the concept of a digital twin in consumer contexts remains loosely defined, which complicates enforcement. Academic researchers at Oxford Internet Institute published a framework in April 2025 distinguishing between preference profiles, behavioral predictions, and full digital twin simulations, arguing that only the latter category, which creates a persistent autonomous model capable of predicting novel decisions, should trigger heightened regulatory scrutiny. That distinction matters for streaming engineers because most recommendation systems operate in the behavioral prediction category rather than full twin simulation. However, the convergence of large language models with user data means the boundary is shifting. A joint report from the Alan Turing Institute and the Ada Lovelace Institute in June 2025 warned that foundation models trained on individual interaction histories could cross into digital twin territory without explicit safeguards, lending academic weight to Onwurah's legislative framing.
