Banyan?

Derek Kite put some interesting points in his blog Freedom and Value. I was surprised to find a reference to Banyan in his post:

....
The high tech industry has not had any trouble generating source code and ideas. It has had trouble generating cash. Those who have been successful may think it is due to having hidden the code. If they were realistic, they would see that the critical elements have been everything else. All else being equal, Microsoft would still own the market even if their code was open from the beginning. Wordperfect would have disappeared when they couldn't move fast enough to develop a suite for Windows. Banyan would still have disappeared when tcpip made them unnecessary. etc etc. When your code becomes valueless, the fact that it is hidden adds nothing.

Are we talking about Banyan Vines from back then? Wow... that was one good network OS.
