The wording in this comment makes it sound like the German goverment was involved a lot more than a 1 year research grant which caps at €47,500 (couldn't find the exact amount they actually got) 4 years into the project that wasn't renewed the next year (not sure if it's even renewable).
I.e. glad to see the funding but it was a one off standard research grant not a special political chess move.
If I understand it correctly, the "Open Knowledge Foundation Deutschland" has received roughly $3 mio in government funding annually to promote "Cyber sovereignty". You are correct that the individual grant to microG was probably capped at €47k, but since they also sent out grant money to
it looks like a coordinated campaign to me. The list includes a privacy-conscious OS, some VPNs, some Tor services, and a Cloud-free translation system for LibreOffice. microG very much fits into that list of tools to avoid Google's spying eye.
