This event might be interesting (it’s organised with the EU-FOSSA2 folks too, who were in FOSDEM): https://ec.europa.eu/digital-single-market/en/news/workshop-about-future-open-source-software-and-open-source-hardware
I’m not sure if there will be any chance of a discussion, but if someone is around it would be useful to remind the attendees about the priorities with free software and what the EC can do (public procurement, antitrust, privacy, phones and other devices for which no fully free operating system is possible etc.).
You can see what kind of stuff the organisers do from the org chart of their departments, DG CNECT/E and DG DIGIT/B:
