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.
does anybody know why libreoffice and not only office? user experience and ms office compatibilty is way better for onlyoffice at leas from my perspective.
Might be the licensing type.
Might also just be what was/is known at the time to the decision makers. I’m in the IT world and didn’t know/learn about ONLYOFFICE until this past year.
