Not only is one German state moving from Microsoft to LibreOffice, but the whole federal government is committing to move to open standards by 2027: https://blog.documentfoundation.org/blog/2025/04/29/germany-committing-to-odf-and-open-document-standards/
Germany committing to ODF and open document standards - The Document Foundation Blog

Digital sovereignty is of vital importance for data freedom. If governments and organisations use proprietary or pseudo-standard formats, they limit the tools that citizens can use to access data. So we’re happy to see that the IT Planning Council in Germany is committing to move to the Open Document Format – a fully standardised format […]

@libreoffice just wish my university would let us submit assignments in .ODF format, as we can only really use Word... and as a Linux user that means Word Online, which is slow and clunky.
@toran Oh no! Ask your uni why they won't accept standardised formats, and force students to use specific software. It's the exact opposite of what unis should be doing. If they say "We use Microsoft Office/365", point out that Microsoft also supports ODF so they should at least accept documents in that format!
@libreoffice
Microsoft support to odf is poor.
@toran
@karlggestd @libreoffice @toran Microsoft's support for ISO OOXML (“their own open standard”) is also poor. So, what?
