The Austrian military prioritizes independence over convenience.
The Austrian Armed Forces (Bundesheer) joined this trend last month by migrating 16,000 workstations from Microsoft Office to LibreOffice, marking a notable shift toward open source alternatives within European defense organizations.
The Austrian military didn't just adopt LibreOffice; they actually contributed back to it. Over five person-years of development work went into adding features they needed. Those improvements are now available to everyone using LibreOffice, which is pretty cool.
Also worth noting is that they were already using self-hosted Linux servers with Samba before this migration, so they weren't deeply locked into Microsoft's ecosystem. That probably made the whole process smoother than it would have been otherwise.
