You stated that very well.

The purpose of copyleft is to defend freedom for all users of our
software.  To defend their freedom requires preventing middlemen
(Cisco in that case) from stripping off the freedom when they
redistribute the software to others.

In other words, when we distribute Emacs to A,
and A redistributes Emacs to B, C and D, copyleft protects
the freedom of B, C and D by requiring
A to pass along Emacs to them with the full four freedoms.
