The German government actually started and funded quite a few projects supporting FOSS development over the past few years. For example, ZenDis was founded in 2022 to develop open-source software for the public administration. They are the driving force behind openDesk, which is shaping up to be a great office- and collaboration suite. Also, there's the Sovereign Tech Agency, where open-source projects can apply for direct funding. The available funds aren't as big as I'd like them to be, but it's not as if there's no funding coming from the German government.
ZenDis has the specific task of improving FOSS software for use by government agencies, so Germany's public administration is simply their primary focus in their development work. I honestly don't have enough experience with different collaboration suites to pinpoint any major feature differences.
Thanks. The software's homepage also cites its target of "public administration," so I'm curious as to what it might lack for private companies or projects.
