Solaris 2.4 (or so) was used on e.g. MCST boxes sold to Russian military before Linux took over.</p>
<p>Sun was burned by a massive leak of SunOS 4.1.3 source code some time in 1994 or thereabouts. I forgot what exact one it was, but an American university had a source lincese and the crackers mounted a repository by NFS from a compromised workstation. From there, it spread quite wide. Although Sun was officially miffed about it and ran audits of licensees, it did not dampen their enthusiasm for source licensing for long, and Solaris was made available after 2.1.</p>

definitely a factor in the early days of Unix (I believe it's why Unix
itself and V7 source licenses were widely and cheaply available before
1982). But after 1982 it didn't restrict AT&T, and post-82 is where
basically all of the System V licensing activity took place. And most
of the commercial Unix vendors date from after that.</p>
<p>(I'm pretty sure that being post-82 (as a Unix vendor) is why SGI's Unix
was based on System V instead of BSD. I don't know how Sun managed to
get a V7 source license; since it was founded in very early 1982, maybe
it just managed to get one before AT&T stopped that.)</p>

That gave the commerical UNIX vendors a head-start.</p>
