I agree that it'd be nice to have that property.  That's the way I had it
initially, but since you need info if it's non-free (the name / TOS), but
not if it is free, the design where free was the default was the simplest.
The alternative was one method indicating it was free/nonfree and the
other, if non-free, to provide the additional information.

I agree that it'd be nice to define this in a more clear way, but we also
can just wait until someone proposes a free LLM to include to judge it.  We
can always bring it back to the emacs-devel list if there is uncertainty.

The hosting code is not that relevant here.  For these companies, there
would be restrictions on the use of the model even if there were no other
unfree software in the middle (kind of like how Llama 2 is).  Notably, no
company is going to want the user to train competing models with their
model.   This is the most common restriction on freedoms of the user.

TIL, that's a great tip, thanks!
