Britain's Competition and Markets Authority opened a formal investigation into Meta on Friday 30 October, examining whether the company's revised commercial terms — which would let it use content from news publishers' websites to build and run its own products and AI features — amount to an abuse of dominance under the Competition Act 1998.

The terms were due to take effect on 20 November. Meta has put them on hold.

The dispute is about consent by default. In the CMA's reading, the clauses would let Meta use collected content in its AI features without publishers and other businesses getting a choice about whether, or how, their content is used. The regulator's phrasing of the concern: requiring businesses to accept the terms could 'amount to an unlawful imposition of unfair trading conditions for thousands of UK businesses.'

'Digital platforms play an important role in helping UK businesses reach millions of customers around the world,' said CMA chief executive Sarah Cardell. 'But where a company holds a dominant position, it must not use that position to impose unfair terms. We've heard concerns from news publishers and other businesses and are acting swiftly to investigate whether Meta's proposed changes may breach competition law.' She stressed the agency wants a 'swift and satisfactory resolution', not necessarily a contested decision.

Meta denies the premise. 'There are no grounds for a competition investigation,' a spokesman said. 'We've already committed not to change our terms without consulting publishers and other stakeholders. We welcome the opportunity to explain our approach to the CMA.'

The timing is not accidental. The CMA this year imposed an obligation on Google to let publishers opt out of feeding their content to its AI features in search. Meta's move is the second attempt by a major platform to obtain publishers' consent through a default clause rather than a negotiation — and it lands weeks before the UK's wider digital-markets regime is expected to start biting.

For publishers the question is familiar from the crawling wars, one layer up: accept the terms and lose control of how the work is used, refuse and risk losing distribution. The Press Association and other publishing bodies brought the issue to the regulator.

What happens next has two stages. First the CMA has to establish that Meta holds a dominant position in a relevant UK market. Only then does the second question arise — whether the terms are in fact exploitative. The investigation can end in commitments, in a prohibition, or in a penalty that under the Competition Act can reach 10 percent of worldwide annual turnover. No timetable has been published; the regulator is promising speed.
