Just FYI, at least 1 of the org-mode extensions (there are a number) for Visual Source Code is licensed under the GPL. So while VS code may not be 'free' in the GNU sense, at least some of the extensions that can be used with it are.

I personally don't see any threat to Emacs Org mode by any of the non-free clones, such as beorg. I doubt there is anything which could be implemented in one of these non-free versions which was of use to Emacs org mode tht we could not re-implement - they would have a tough time try8ing to argue that it was original work and attempt to stop an elisp version.

Of course, this says nothing about the ethical position associated with re-implementing functionality from a GPL'd sysem under a non-free license. We can hope people do the right thing, but have no control to enforce it. I also doubt it will cause any fracture in the org user community - the bottom line is most of use came to org because of Emacs. These other systems don't have Emacs and therefore are really only a pale imitation. .

It is great that people want to implement Org functionality into other software, but the issue I have with beorg and Visual Source Code is that neither is free software. In the case of beorg, Org is mentioned repeatedly on its website as an inspiration, but what is the contribution of the beorg developers back to the Org community? The central feature of Org is that it is free software. In my view, non-free products like beorg are fundamentally broken.

I agree with this completely.

It would be wonderful to see new good ideas implemented in other systems, but in the case of proprietary software like beorg or Visual Source Code, their non-free nature makes it risky to re-implement in Org any new ideas they use (if they ever use any). I hope all the new good ideas for Org first exist as free software. That seems likely given the pace at which Org develops and the vitality of the Org community.
