A look at the US and EU's dueling approaches to rein in Big Tech, splitting tech companies' attention by miring them in separate legal and enforcement battles
The West's key regulators are now fully on the offensive against Apple, Google and other giants they see as monopolies. Threads: @marks.wiki . X: @tomhebertdc Threads: Mark Davis / @marks.wiki : In 5 years, Microsoft will be in an Anti-Trust battle about Copilot being the Default AI in Windows. EU will force them to allow folks to pick a default AI. X: Tom Hebert / @tomhebertdc : In this story, a former bureaucrat says that collusion between U.S. and EU bureaucrats to undermine American companies is a “one-way ratchet.” I doubt it. @SpeakerJohnson recently blasted the collusion, which is under numerous Congressional probes, as “against our interests”👇 [image]
Context & Ripple Effects
The story sits after a period in which large platforms had already shifted from trying to reshape EU rules to preparing for compliance as the Digital Markets Act neared completion. It also follows growing expectations of tougher U.S. oversight under the Biden administration, reflected in Big Tech's preparations for a stricter regulatory climate.
What matters is not simply more antitrust scrutiny, but the operational burden of navigating separate U.S. and EU legal and enforcement tracks at once. Apple, Google and other major platforms must divide executive attention between jurisdictions whose priorities and remedies may not align.
First-order effects
- Apple, Google and other targeted platforms face parallel legal, policy and compliance workstreams, increasing the management attention required to respond to regulators on both sides of the Atlantic.
- The companies' product, distribution and business-practice decisions become more exposed to jurisdiction-specific enforcement, rather than being addressed through a single Western regulatory strategy.
Second-order effects
- Regulatory fragmentation raises the value of region-specific compliance, legal and policy operations, while making it harder for platforms to use one change or defense across their major Western markets.
- The scrutiny creates a clearer pathway for challenges to default positions and platform control points; the article's Copilot example suggests AI defaults could become the next contested distribution mechanism.
Third-order effects
- If U.S. and EU enforcement continue to diverge, global platforms may increasingly organize products and governance around regulatory blocs rather than a uniform market model.
- Antitrust oversight is broadening from established platform power toward control over emerging AI distribution. Whether that produces aligned remedies or a more durable transatlantic split remains contingent on regulators' future choices.
The trend: Big Tech regulation is evolving into a multi-jurisdiction contest over platform gatekeeping and, increasingly, the default distribution of AI services.
