BTW:  I just thought of something else....  one of the b*tched about the
commercial redistribution license from V7 in 1979, that was not fixed until
the SVR3 licensing the mid-late 1980s  was AT&T's source policy.   As I
said, a commercial source license was $20K for the first CPU and 5K for
each additional one.   Later (System V) it went to $50K for the first and
$10K for each additional.   But what really ticked off the vendors like
DEC, Masscomp, Sun et al, was that each system that sources on was supposed
to one of the 'second CPU licenses' - the binary license was not good

What most of us did, was make sure any system that was a 'source control'
or 'master' system at any 'site' had a full source license, but we were all
in violation of the source agreement on our personal workstations.  The
argument was the sources on people's machines was ephemeral and not
'stored' there.   But it was definitely contentious.
