Any nonfree program that users can install to run in a subprocess,
they can easily arrange to communicate with through sockets over the
net. Thus, supporting a case of (b) implies supporting also the
scenarion (c).
So, if our rules say that (b) is ok in a certain case, we need not worry
separately about (c).

Based on the details you gave, I think we are miscommunicating.
You're saying that a Lisp program communicates with the Oracle
database through calls to other Lisp packages -- but that doesn't
address this question. Those other Lisp packages are free
and running inside Emacs.
This question is how Emacs communicates with the Oracle database
program.

If it uses comint mode, it is talking with that program
through a pty or pipe. So the answer is c.

But this text from a doc string makes me concerned

because it isn't clear. It is sketchy. An expert on running that
database on Windows might understand it, but someone who only knows
about Emacs can't even try.
How does sql.el communicate with sqlplus on Windows?
