In boardrooms across Copenhagen and Berlin, government ministers in Europe are quietly planning the largest corporate breakup in decades. Denmark’s Ministry of Digital Affairs will phase out Windows and Office 365 by November 2025.
Germany’s Schleswig-Holstein declares “We’re done with Teams”. What Europe is ditching Microsoft for runs deeper than software preferences.
When Digital Sovereignty Trumps Corporate Convenience
Behind closed doors, European officials worry about American tech giants controlling their most sensitive data. The slow decoupling reflects growing unease about transatlantic power imbalances. Denmark and Germany are not acting alone in their digital rebellion.
Three fundamental forces are driving the continental shift. European governments increasingly view American software as a sovereignty risk.
Data protection laws like the General Data Protection Regulation make compliance harder for US firms. Budget pressures make open-source options more attractive than expensive licences.
Seven Countries Leading the Great Disconnect
Across the continent, governments are switching to Linux and LibreOffice with remarkable speed.
France pioneered the movement years ago with its police force. Italy followed with educational institutions making the leap. Estonia built entire e-governance systems on open-source foundations.
What the slow decoupling means for euro-american business ties becomes clearer when examining the case studies. Each transition reduces European dependence on Seattle-based software. Local tech firms benefit as governments seek out homegrown options.
The European Data Protection Supervisor recently found the European Commission breached data protection rules using Microsoft 365. Such regulatory friction accelerates the departure process.

How Microsoft Fights Back Against European Exodus
Microsoft responds with new European digital commitments and sovereign cloud systems. The company promises to store European data within EU borders. The efforts may slow but cannot stop the underlying trend.
Critics claim Europe’s digital independence drive will fragment global technology standards. They warn about reduced interoperability between American and European systems. Some economists predict higher costs for European businesses using different software from their American partners.

Why Europe Won’t Back Down From Digital Independence
Such concerns disregard what’s driving European policy makers.
Digital sovereignty stands for national security as much as economic policy. Europe learned hard lessons about energy dependence during recent geopolitical crises. Tech dependence carries similar risks in an interconnected world.
Europeans remember how quickly political winds can change transatlantic bonds.
What happens when the next American administration takes a harder line on data sharing? European governments prefer controlling their own digital destiny rather than hoping for continued cooperation.
Building Bridges Through Open Standards
Forward-thinking European and American firms can turn the decoupling into opportunity rather than crisis. Open standards enable interoperability without vendor lock-in. Companies investing in platform-agnostic systems will thrive as markets fragment.
The smartest businesses are already adapting to the new reality. They develop software that works equally well on Microsoft Windows and Linux systems. Cloud services that respect European data sovereignty while maintaining global connectivity will capture growing market share.
What Euro-American Business Leaders Must Do Now
Preparing for the digital divorce requires concrete action from corporate boardrooms.
American firms should invest heavily in European data centres and local partnerships. European companies must evaluate their software dependencies and plan gradual transitions where needed.
Soon, Copenhagen’s civil servants will use LibreOffice instead of Word. Berlin’s officials will replace Teams with open-source chat tools. Munich’s administrators will run Linux rather than Windows on their desktops.
