I mean the conflict in the other code base is that an implementation of any kind exists.

The feature set of the paid version is public information.

Surely authors already know this before writing their code?

What I'm saying is that there are probably many, many authors who realise that and wouldn't risk contributing (therefore having a chilling effect). Kinda makes the project "open source-ish". All the legal infrastructure, none of the community norms.
