A German state government is ditching Microsoft Office and Windows to embrace open-source and free alternatives LibreOffice and Linux.

Germany’s Schleswig-Holstein province announced the change as part of a push for "digital sovereignty," or the ability to control the country’s technology and data. The state government says it’s "switching away from proprietary software and towards free, open-source systems” for approximately 30,000 employees. 

“In addition to improved IT security, cost-effectiveness, and data protection, the use of open-source software also enables seamless collaboration between different systems,” officials say. “Alongside open-source software development, the goal is to release future development results of the country under free licenses.”

The state government doesn't call out Microsoft directly, but it says proprietary software can be “significantly restricted in their use and further processing due to copyright and licensing conditions.”

“We have no influence over the operational processes of such solutions or the handling of data, including the possibility of data outflows to third-party countries,” the state government adds. 

LibreOffice celebrated the announcement as a major win. “ Why should local governments use taxpayers’ money to buy proprietary, closed software from a single vendor?” it asked in a blog post. “With LibreOffice and free software, administrations have much more choice where to get the software and support, and can fund local developers to make improvements.”

It’s possible other government agencies in Germany could make the switch too. Schleswig-Holstei’s government intends on being a pioneer in the region by becoming the first state “to introduce a digitally sovereign IT workplace in its state administration.”

Earlier this month, the European Commission also ruled that its use of Microsoft 365 infringed on data protection laws.

The decision, however, comes shortly after Microsoft software engineer Andres Freund noticed a backdoor in XZ Utils, an open-source set of data-compression tools widely used across Linux and Unix-like operating systems. He caught it in time, but the incident highlights the need to secure open-source software, which is often maintained through volunteer contributors.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
