Where's the (c) on UNIX?

[John Haller]

A good place to ask about trade secret protection is cca!z,
as he ran into that problem in that his emacs was derived
from Montgomery's emacs, which is AT&T Bell Laboratories Proprietary,
otherwise known as trade secret.  How was AT&T able to force CCA
to request that everyone that had a copy of CCA emacs to remove it?
What if someone refused that request.  Does AT&T have any
means of forcing the receipients of that emacs to remove
all copies of it?
