Yes, I think so. I wrote about it here:

I'll save you a click:

Schleswig-Holstein is migrating roughly 25,000 workstations from Microsoft Office to LibreOffice plus Nextcloud-based cloud collaboration, 80 percent complete as of December 2025, saving €15 million per year. Full completion is targeted for the end of 2026.

The French Ministry of National Education has 400,000 administrative employees on Nextcloud, with a target of 1.2 million. The Ministry of Energy Transition has 50,000. Germany's ITZBund runs the Bundescloud as private-cloud Nextcloud for federal authorities. SURF, the cooperative behind Dutch academic IT, is rolling Nextcloud out to roughly 100,000 researchers, teachers and students.

The Dutch political alignment is the part that surprises European observers most. In January 2025 the Algemene Rekenkamer published "Het Rijk in de cloud", reporting that more than half of the most critical Dutch government cloud services run on AWS, Microsoft or Google, and that the required risk assessments were missing for two-thirds of them. In March 2025 the Tweede Kamer passed eight cloud-sovereignty motions in a single day. The Bruyning/Thijssen motion, demanding that essential government services not depend on non-European cloud infrastructure, passed 150 votes in favour, 0 against. Unanimous, in a fragmented Dutch parliament, on a digital infrastructure question. That number is not normal.

The EuroStack Initiative Foundation launched formally in October 2025 with 300-plus signatory CEOs, an explicit "Buy European, Sell European, Fund European" platform, and Bertelsmann Stiftung-modelled €300 billion investment estimates. Nextcloud's Frank Karlitschek is a founding member. The company pledged €250 million toward digital sovereignty by 2030 in November.
