Absolutely true, but there was a bit more work needed than just the 
preliminary ruling. In parallel, the TUHS folk were petitioning old SCO 
(not TSG) to release the ancient Unixes under a BSD-style license: 
https://www.tuhs.org/PUPS/petition.html. Eventually old SCO agreed to a 
BSD-style hobbyist license which cost US$100:

Some details of the process are here: 
https://www.tuhs.org/PUPS/pstatus.html.

Then a while later, Caldera (who had bought the Unix licensing from old 
SCO) offered their $0 license:

I want to give a shout out to Dion Johnson who was the driving force at 
old SCO that finally got them to agree to putting the ancient Unixes 
under a BSD-style license.

Cheers, Warren
