It used to be said that the sun never set on the British Empire, so far-flung were its possessions. Britain has long since retreated from most of those territories, most recently, and controversially, in its attempt to relinquish control of the Chagos Islands. Yet even as it sheds physical dominion, Britain appears increasingly eager to export something else: its laws and regulations.
In that project, it is joined enthusiastically by its former partners in the European Union. If the Old World has one major export left, it is bureaucracy.
The most obvious current target is X, Elon Musk’s platform, and its Grok AI tool. Some users of questionable taste quickly discovered that Grok could be used to generate deepfake images of celebrities in revealing attire. More seriously, it was alleged that the technology had been used to generate sexualised images of children. In response, last month the UK’s communications regulator, Ofcom, opened a formal investigation under the Online Safety Act, citing potential failures to prevent illegal content. The possible penalties are severe, ranging from multi-million-pound fines, based on the company’s global revenue, to a complete ban on the platform in the UK.
Senior British officials were quick to escalate the rhetoric. Prime Minister Keir Starmer and Technology Secretary Liz Kendall publicly condemned X and emphasised that all options, including nationwide blocking, were on the table. The message was unmistakable; compliance would be enforced, one way or another.
Two days later, X announced new restrictions to prevent Grok from editing images of real people into revealing scenarios and to introduce geo-blocking in jurisdictions where such content is illegal. Ofcom described these changes as “welcome” but insufficient, insisting its investigation would continue. Meanwhile, pressure spread outward. Other governments announced restrictions, and the European Commission expanded its own probes under the Digital Services Act. What began as a British enforcement action quickly morphed into coordinated global pressure, effectively pushing X toward worldwide policy changes.
This is the crucial point. British regulators were not merely seeking compliance for British users. They were pressing for changes to X’s global policies and technical architecture to govern speech and expression far beyond the UK’s borders. What might initially have been framed as a failure to impose sensible safeguards on a powerful new tool has become a test case for whether regulators in one jurisdiction can dictate technological limits everywhere else.
This pattern is not new. Ofcom has already attempted to extend its reach directly into the United States, brushing aside the constitutional protections afforded to Americans. Since the Online Safety Act came into force in 2025, Ofcom has adopted an aggressively expansive interpretation of its authority, asserting that any online service “with links to the UK,” meaning merely accessible to UK users and deemed to pose “risks” to them, must comply with detailed duties to assess, mitigate, and report on illegal harms. Services provided entirely from abroad are explicitly deemed “in scope” if they meet these criteria.
The flashpoints have been 4chan and Kiwi Farms, two US-based forums notorious for unmoderated speech and even harassment campaigns. In mid-2025, Ofcom initiated investigations into both for failing to respond to statutory information requests and for failing to complete the required risk assessments. It ultimately issued a confirmation decision against 4chan, imposing a £20,000 fine plus daily penalties for continued non-compliance, despite the site having no physical presence, staff, or infrastructure in the UK.
Rather than comply, the operators of both sites filed suit in US federal court, arguing that Ofcom’s actions violate the First Amendment and that the regulator lacks jurisdiction to enforce British law against American companies. The litigation frames the dispute starkly: whether a foreign regulator may, through regulatory pressure, compel changes to lawful American speech.
That question has now spilt into US politics. Senior American officials have criticised Ofcom’s posture as an extraterritorial threat to free speech, and at least one member of Congress has threatened retaliatory legislation. What Britain views as online safety increasingly appears, from across the Atlantic, to be regulatory imperialism.
