Scott is rewriting history
Scott McNealy wants us to believe that dealing with ATT to merge SunOS with System V made
Sun a closed source company because, as a result, it could not open source Solaris.
Facts prove that at this time Sun was fiercely closed source, turning its back on its BSD background. The reality is that Open Source was considered an option only on the light of
the success of linux, that is after 2000.
But at the end of the eighties, Sun was closed source and tried to be too greedy.
Around 1988, Sun decided to unbundle the C compiler that was until then given with SunOS.
As a result, most people switched to gcc and many people who could live with free proprietary tools got a taste of Open Source tools (even if the term was not yet coined).
The reality is that the infusion of cash from ATT made Sun arrogant. That turned all the Unix industry against Sun. At that time, Sun was trying to push NeWS, its Network extensible Windows System.
The rest of the Unix industry pushed the Open Source X window System to kill NeWS and succeeded. That is why today most Unix System (except for Apple) run this X crap.
NeWS was based on the superior PostScript imaging model but free of Adobe proprietary code.
Had Sun opened the NeWS code, the story may have been different.
