Hmm ..I thought all of the majors >>except<< for DEC​ bought out their
licenses at some point.   I admit I've forgotten the specifics, but  that
is my recollection.

​HP/UX is an SVR3 & OSF/1 ancester.   Solaris is SVR4.  In fact it was the
SVR4 license and deal between Sun and AT&T)​ that forced the whole OSF
creation.  One of the "principles" of the OSF was "Fair and Stable" license
terms.

Which begs a question - since Solaris was SVR4 based and was made freely
available via OpenSolaris et al, does that not make SVR4 open?   I'm not a
lawyer (nor play one on TV), but it does seem like that sets some sort of
precedent.

​Interesting - how did they "scrub" SVR4 from it?   The whole idea was to
take SVR4 and "enhance it" using the SVR4 API's.  ​

​Agreed, unless there is a clear statement from the owners, it's going to
be hard; which is a shame from a historical stand point, but I agree.
