A couple of "for instance" here might help. Tru64 is a derivited work from
a lot of places, a big one being the OSF/1 kernel which was based on the
CMU Mach uKernel. CMU had made rhe Mach ukernel "open source" and gave it
away - but the license did says to hd say you work was based on something
you got from CMU. OSF and DEC used that technology and now DEC is long
gone, but getting the DEC sources is difficult [unless the owners of that
IP - in this case HP - some how released it]. Ultrix is in the same
camp, or for that matter the DG rewrite of System V [which was one of the
best pure Unix implementations for a SMP system]. Similarly, OSx (darwin
etc) is also based on Mach, BSD etc.. At one time, Apple did chose to
make darwin available, but not all of the latest enhancements from Apple
have been made available.
OSF/1 1.0 and 2.0 sources ended up out somewhere...as I have sources to
them. I have DG/US as well.
Doesn't mean I can legally DO anything with it, though.
Apple are largely removing GPL'd stuff and going to differently-licensed
stuff.
