Code bases are on GitHub and they use English there: https://github.com/suitenumerique/

Not French and I can't say I personally tried deploying any of them, but I've been admiring their efforts from afar for a while now.
1.5 year ago DINUM (La Suite) and OpenDesk (Germany) reached out and started sponsoring quite a bit of our work which has really helped us accelerate the project
And I believe BlockNote uses tiptap/prosemirror, no? Do they also contribute to those “primitives”? That would be a very nice gift to the OSS community
We're discussing how to work best with downstream dependencies as well. So far they're actively sponsoring Yjs, but not prosemirror/tt.
fyi, here are some early thoughts by the PM of Docs on how to collaborate between public sector and OSS (companies): https://github.com/virgile-dev/playbook-work-with-oss-librar... (we surely don't check all the boxes yet, but it's good to have the discussion!). Feel free to jump in!
