Why doesn't the open source nknx work, it's not complete? Why not fully open source?

First of all, I am very happy that nknx can return and open source, but I can’t understand why only part of it can be open source? When will it be fully open source.

Hey there,
Everything is open-sourced in the repo. What are you missing or what doesn’t work?
Also, I will be building NKNx in public live streams starting in March.
But until then I’d be happy to answer questions here.
