EU defends digital rules after Trump threatens tariffs over DSA and DMA

The European Commission on Tuesday rejected US demands to water down its digital rulebook, declaring that the right to regulate technology companies operating on European soil is a sovereign prerogative that will not be traded away. The statement came hours after Donald Trump posted on Truth Social that he would impose "substantial additional Tariffs" and place export restrictions on technology and chips on any country whose digital policies he judged discriminatory toward American firms.

The escalation landed less than a week after the EU and the United States issued a joint statement formalising a provisional tariff truce struck at Turnberry, Scotland, in late July. That agreement had been intended to pause a spiral of retaliatory duties while negotiations continued. Trump's missive, which accused the EU of using its laws to attack "incredible American Tech Companies" and declared that America would no longer be a "piggy bank" or "doormat", suggested the ceasefire was already fracturing.

Brussels frames regulation as democratic sovereignty

At the Commission's daily briefing, spokesperson Paula Pinho delivered the institution's core message: "It is the sovereign right of the EU and its member states to regulate economic activities on our territory, which are consistent with our democratic values." The formulation was deliberate. By invoking democratic values, Brussels signalled that the Digital Services Act (DSA) and the Digital Markets Act (DMA) are not merely technical standards but expressions of political choices made by elected legislators in the European Parliament and the Council.

Thomas Regnier, another Commission spokesperson, reinforced the point by stressing the neutrality of the two regulations. "The DSA does not look at the color of a company, at the jurisdiction of a company, nor the owner of a company," he said. "The DSA and the DMA both apply to all platforms and companies operating in the EU irrespective of their place of establishment." He added that the last three enforcement decisions taken under the DSA targeted AliExpress, Temu and TikTok, two Chinese-owned platforms and one owned by ByteDance, rather than any US giant.

What the DSA and DMA actually require

The DSA, which entered into force in November 2022 and became fully applicable in February 2024, imposes a tiered set of obligations on online intermediaries. The most stringent requirements fall on very large online platforms and very large online search engines, services with more than 45 million monthly active users in the EU. Those firms must conduct annual systemic risk assessments covering illegal content, fundamental rights, civic discourse, public health and minors, and they must mitigate identified risks. They are also required to provide researchers with data access and to submit to independent audits.

The DMA, applicable since May 2023, targets a different problem: market power. It designates "gatekeepers", companies that provide core platform services such as operating systems, app stores, search engines, social networks and video-sharing platforms, and subjects them to a list of do's and don'ts. Gatekeepers must allow third-party app stores, enable data portability, refrain from self-preferencing their own services, and give business users access to performance data. The Commission has so far designated six gatekeepers: Alphabet, Amazon, Apple, ByteDance, Meta and Microsoft.

Enforcement record undermines discrimination claim

Regnier's reference to recent enforcement actions was not incidental. The Commission's first three formal DSA investigations opened in 2024 concerned AliExpress (suspected failures on risk assessment and mitigation for illegal products), Temu (similar concerns plus issues with recommender systems and dark patterns) and TikTok (risks linked to the "Lite" reward programme and protection of minors). A fourth, opened in October 2024, targets X over suspected failures in content moderation, dark patterns and data access. Only the X case involves a US-headquartered company, and even there the Commission's concerns centre on systemic risk processes rather than the content of speech.

Under the DMA, the Commission opened non-compliance investigations in March 2024 against Alphabet, Apple and Meta. Those proceedings focus on specific technical obligations, steering rules in app stores, default browser choice screens, interoperability for messaging, not on the nationality of the firms. The pattern is consistent: enforcement follows the statutory criteria, not the flag of the company.

Trade chief says rules are not bargaining chips

Speaking at the European Forum Alpbach in Austria, Sabine Weyand, the Commission's director-general for trade, struck a firmer tone than the daily briefing. "We have always been very clear, our regulation is nondiscriminatory and we will apply it as decided by our democratic institutions. That is not up for concessions or negotiations with other countries. That doesn't change," she said. Weyand acknowledged that "successive US administrations" have expressed concerns about EU digital rules, but she framed the current friction as a familiar feature of the transatlantic relationship rather than a new crisis.

Her remarks reflect a calculation in Brussels: the EU believes its regulatory model has become a global reference point, copied in whole or in part by jurisdictions from the UK to Brazil, Japan and Australia. Conceding ground to Washington now would undermine that influence and invite demands from other capitals. The Commission also judges that the US tech lobby, while vocal, does not speak for the entire US government; the Biden administration had its own criticisms of the DSA and DMA but never threatened tariffs over them.

Common ground on safety, divergence on speech

Both Regnier and Weyand were at pains to highlight areas of agreement. "When we talk about the DSA, it's protection of kids online, the protection of election integrity online. We have a lot of points where we are actually working hand in hand with the US," Regnier said, adding that disagreements concern only "very tiny aspects" of the legislation. The Commission points to the EU-US Trade and Technology Council, which has produced joint roadmaps on evaluation and measurement tools for trustworthy AI, and to coordinated actions against foreign information manipulation.

The "tiny aspects" euphemism masks a deeper philosophical divide. The US tradition, anchored in the First Amendment and Section 230 of the Communications Decency Act, treats platform liability for user-generated content as an exception. The EU model, codified in the DSA, treats systemic risk mitigation as a positive obligation. For Washington, the DSA's risk assessment and mitigation requirements look like state-supervised content moderation; for Brussels, they are consumer protection and democratic resilience. That gap is not easily bridged by technical working groups.

Tariff threat raises legal and economic questions

Trump's threat to impose tariffs and chip export restrictions in response to digital regulation raises immediate legal questions. The World Trade Organization's General Agreement on Trade in Services (GATS) and the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) both constrain the use of trade measures to achieve regulatory objectives. The EU could argue that unilateral tariffs targeting a specific regulatory regime constitute a violation of most-favoured-nation treatment or national treatment obligations. The Commission has not yet indicated whether it would challenge such measures at the WTO, but officials privately note that the EU's own anti-coercion instrument, which entered into force in December 2023, provides a framework for countermeasures against economic pressure from third countries.

Economically, the stakes are asymmetric. US tech firms derive a significant share of global revenue from the European market, Meta reported that Europe accounted for roughly 23% of its advertising revenue in 2023, Alphabet about 18%. The EU, by contrast, has no homegrown platforms of comparable scale. Tariffs on technology and chips would hit European manufacturers and consumers as well as US exporters. The Turnberry truce had been designed to avoid precisely this kind of tit-for-tat escalation in high-value sectors.
