France just declared independence from Microsoft. On April 10, the government announced it’s migrating all 2.5 million civil servant desktops from Windows to Linux by 2030—the largest government tech migration in European history. This isn’t a pilot program testing alternatives. It’s a €3 billion commitment to completely eject American software from French government infrastructure.
And France isn’t alone.
Europe’s Coordinated Breakup with US Tech
Germany, Austria, Denmark, and Italy are executing parallel Microsoft exits right now. Germany’s Schleswig-Holstein region completed its migration in 2025, moving 44,000 government email accounts off Microsoft and saving €15 million annually. Austria’s armed forces finished a four-year Office exodus. Italy migrated 150,000 Ministry of Defense PCs to LibreOffice. The Netherlands launched Office.eu this year—a commercial LibreOffice offering targeting businesses beyond just government.
This is coordinated at the EU level. In April, the European Commission awarded its €180 million sovereign cloud framework contract to four European providers: Scaleway, OVHcloud, StackIT, and a Proximus-Thales consortium. AWS applied but didn’t make the cut. When the EU explicitly excludes Amazon from a major infrastructure contract, that’s not a technical decision—it’s a political one.
The numbers tell the story: 61% of European CIOs say they’re increasing use of local cloud providers, and EU sovereign cloud spending is growing 83% year-over-year. This is an industry restructuring, not a trend.
The US CLOUD Act Problem That Won’t Go Away
Europe’s public narrative is “digital sovereignty.” The technical reason is simpler and more damning: US law fundamentally conflicts with EU data protection requirements.
The US CLOUD Act, passed in 2018, allows American law enforcement to compel US companies to hand over data stored anywhere in the world—including European data centers. That Microsoft Frankfurt facility housing German government data? Still subject to US legal jurisdiction because Microsoft is a US company. The EU Data Act and GDPR explicitly prohibit exactly this kind of third-country government access. These laws cannot coexist.
France’s Health Data Hub migration from Azure to Scaleway, announced April 24, cited the CLOUD Act specifically. National health data is among the most sensitive information governments hold. When France moves that data off Azure with a €20 million budget, they’re stating clearly: we cannot comply with EU law while using US cloud providers.
This isn’t protectionism dressed up as security. It’s a legitimate legal incompatibility with no technical fix.
The Economics Might Actually Favor Open Source
Here’s what nobody wants to admit: the sovereignty narrative obscures a simple question about vendor lock-in costs. Schleswig-Holstein’s €15 million annual savings from ditching Office 365 suggests Microsoft’s pricing might be the real problem.
Independent benchmarks show Scaleway delivers 4.8 times the compute value per euro compared to AWS. Real-world deployments report 40-60% total bill reductions for identical workload capacity. When you add up egress fees—which 99% of cloud storage users pay—the hyperscaler cost advantage evaporates.
But migration costs are brutal. France estimates €1.5-3 billion over five to seven years, or roughly €600-1,200 per desktop all-in. That includes hardware upgrades, retraining 2.5 million civil servants, dealing with application compatibility nightmares (Adobe Creative Suite, AutoCAD, and Excel macros don’t run on Linux), and absorbing productivity losses during the transition.
One documented case: a user spent 72 hours migrating to Linux, only to discover three critical business applications lacked compatibility. Replacement cost exceeded €8,000, excluding lost productivity. Scale that across 2.5 million workers and the risk becomes clear.
The break-even calculation: if France achieves Germany-scale savings, they’ll recoup costs in three to five years. But that assumes a smooth migration, which almost never happens at this scale.
The Developer Job Market Just Split
EU government contracts now require Linux and open source expertise instead of Windows and Azure certifications. This is happening fast enough that most IT staff haven’t adapted—France noted most government administrators “worked exclusively with Windows environments throughout their careers.”
That skills gap is a market opportunity. European cloud providers are hiring aggressively. Scaleway, OVHcloud, and StackIT are expanding infrastructure across 13+ countries through the €75 million EURO-3C project. AWS and Azure certifications that were career assets in Europe six months ago are becoming less relevant for public sector work.
The open source community is benefiting directly. The Document Foundation, behind LibreOffice, calls this “a growing push to use public money for public code.” When governments contribute development resources back to projects they depend on, the entire ecosystem improves.
But let’s be clear about what’s happening: this is tech de-globalization. The EU is building a parallel infrastructure stack explicitly designed to exclude American companies. Whether that succeeds depends entirely on execution—and large-scale government IT migrations have a poor track record.
The political decision is made. The technical question is whether Europe can actually pull this off.
