There is a moment in the life of any dependency when the dependent party recognizes, suddenly and with clarity, the nature of the relationship. For European governments, that moment arrived when Microsoft canceled Karim Khan’s email.
Khan is the chief prosecutor of the International Criminal Court. In late 2025, the Trump administration imposed sanctions on him personally in response to ICC investigations. Microsoft, complying with U.S. sanctions law, terminated Khan’s access to his Microsoft email account. The prosecutor of an international tribunal established by treaty, investigating alleged war crimes, lost his email because an American company decided he should.
The implications rippled through foreign ministries, intelligence agencies, and government IT departments across Europe. If Microsoft could cancel the ICC prosecutor’s email at the command of the American executive branch, what else could American technology companies do? What communications could they intercept? What services could they terminate? What “kill switches” existed in the infrastructure that governments had come to depend upon?
Last week, France announced that it would ban Zoom and Microsoft Teams for public officials, replacing them with a domestically developed platform called Visio. The announcement is the most visible manifestation of a deeper shift: democratic nations are reconsidering their dependence on American technology platforms in ways that would have seemed paranoid five years ago and now seem prudent.
The Timeline of a Reckoning
The French announcement follows years of escalating concern.
In 2020, the European Court of Justice struck down Privacy Shield, the framework governing transatlantic data transfers, ruling that American surveillance law provided insufficient protection for European citizens’ data. The decision, known as Schrems II, created legal uncertainty for every European organization using American cloud services.
In 2022, the European Commission proposed the Data Act, establishing rules for data sharing and limiting international data transfers. The regulation reflected growing concern that European data processed by American companies was subject to American jurisdiction in ways that European governments could not control.
In 2025, the sanctions on the ICC prosecutor demonstrated that these concerns were not theoretical. American companies would comply with American government demands, regardless of the impact on foreign customers. The “kill switch” was real.
French Minister Delegate David Amiel stated the rationale plainly: maintaining classified exchanges and strategic information on external infrastructure poses an unacceptable national security risk. The question was not whether American platforms were convenient or cost-effective. The question was whether French government communications should be subject to the potential control of a foreign power.
The answer was no.
The Visio Alternative
Visio is not new. The platform has been in testing for approximately a year and already supports around 40,000 users within French government networks. It is hosted on Outscale’s sovereign cloud, a subsidiary of Dassault Systèmes, ensuring that all user data remains within French jurisdiction. The encryption keys are French. The servers are French. The legal framework governing access is French.
France announced that it will roll out Visio across all government departments by 2027. Leading adopters include the CNRS (French National Centre for Scientific Research), which will replace 34,000 Zoom licenses by March 2026, along with the French National Health Insurance Fund, the Directorate General of Public Finances, and the Ministry of Armed Forces.
The economic case is straightforward. France projects €1 million in annual savings for every 100,000 users migrating from licensed American solutions. For a government employing millions, the savings are substantial. But the primary motivation is not financial. It is strategic.
The Broader European Context
France is not acting alone.
The European Union has been constructing a regulatory framework to assert control over digital infrastructure for years. The Digital Markets Act imposes obligations on large platforms designated as “gatekeepers.” The Digital Services Act establishes content moderation requirements. The GDPR created the world’s most stringent data protection regime.
These regulations represent an attempt to exercise sovereignty over digital space without building alternative infrastructure. They regulate American platforms operating in Europe rather than replacing them. The French decision represents a different approach: building domestic alternatives and migrating away from American platforms entirely, at least for government functions.
Other European nations are watching. Germany has expressed similar concerns about digital sovereignty. The Netherlands has conducted assessments of risks associated with American cloud providers. The UK, despite its closer alignment with the United States, has begun examining the security implications of platform dependence.
Beyond Europe, the backlash is global. India has endorsed “Made in India” alternatives to American platforms. Australia has examined social media platform risks. International organizations have begun diversifying their technology providers to avoid the vulnerability that the ICC prosecutor experienced.
The American Perspective
From an American perspective, this development is strategically problematic but legally predictable.
American technology companies operate under American law. When the American government imposes sanctions, American companies must comply or face criminal penalties. Microsoft did not choose to cancel Khan’s email because it wanted to. It complied with legal requirements imposed by the executive branch.
The same logic applies to surveillance. American intelligence agencies have broad authorities to compel American companies to provide data, particularly data involving foreign nationals. The CLOUD Act of 2018 clarified that American companies must provide data to American law enforcement regardless of where the data is stored. European data on American platforms is American data for legal purposes.
This is not a bug in American law. It is a feature. American policymakers deliberately constructed a legal framework that extends American jurisdiction to data processed by American companies worldwide. The framework serves American intelligence and law enforcement interests.
The consequence is that foreign governments now recognize what American law always implied: using American platforms means accepting American jurisdiction. For routine commercial purposes, this may be acceptable. For sensitive government communications, it increasingly is not.
The Technology Nationalism Question
Critics will characterize the French decision as technology nationalism, a retreat from the globalized digital economy that has generated enormous value over the past decades.
The critique has merit but misses the strategic context. Technology is not neutral. The platforms through which governments communicate, store data, and conduct operations are infrastructure as critical as roads, ports, and power plants. No serious nation would allow a foreign power to control its physical infrastructure. The question is why digital infrastructure should be different.
The honest answer is that it should not be different, and nations are belatedly recognizing this reality.
The American government understood this long before European governments did. American defense and intelligence agencies do not use foreign platforms for sensitive communications. American sanctions law reflects an understanding that technology control is a form of power. American policy has consistently sought to maintain American dominance over global digital infrastructure.
European governments are now applying the same logic in reverse. If technology control is power, then dependence on American technology is subordination. Strategic autonomy requires technological autonomy, at least for critical government functions.
The Market Implications
For American technology companies, the French decision represents the beginning of a trend that will accelerate. Government contracts in democratic nations outside the United States will increasingly require sovereign infrastructure. The addressable market for American platforms in sensitive applications is shrinking.
This creates opportunities for European technology companies that can provide sovereign alternatives. It creates opportunities for American companies willing to establish genuinely independent subsidiaries operating under local legal frameworks. It creates complexity for multinational organizations that must now navigate diverging technology ecosystems.
The fragmentation of the global digital market along national and regional lines was always a possibility. American platforms benefited from a period of relatively uncontested global expansion. That period is ending. The kill switch that canceled Khan’s email demonstrated the risks of dependence, and nations are responding rationally by reducing that dependence.
What This Means for Everyday People
For ordinary citizens in France and elsewhere, the shift to sovereign platforms will be largely invisible. Visio will replace Zoom in government offices. Most citizens never attended those meetings anyway.
The deeper implications are systemic. The fragmentation of the global digital economy into sovereign blocs will reduce efficiency and increase costs. Interoperability between national systems will be imperfect. The seamless global communication that characterized the internet’s first decades will become more constrained.
Whether this is a price worth paying depends on values that reasonable people weigh differently. Privacy and sovereignty have costs. Convenience and efficiency have costs. The Khan incident forced a reckoning with tradeoffs that had been deferred, and nations are making choices about which costs they are willing to bear.
France has chosen sovereignty over convenience. Other nations will make their own calculations. The era of unquestioned American dominance over global digital infrastructure is ending. What replaces it remains to be determined.
