Yes but Cathedral and the Bazaar was telling us that the world had changed, gcc was free, linux was a thing etc, mainframes (where compilers cost $10k and you (mostly) couldn't bring your own OS) were being replaced by workstations etc.

Commercial access to Unix source was still many thousands of dollars, the whole SCO debacle was an attempt to stop free OSs from being a thing

Many of us who had grown up from the mainframe era wanted to write compilers, work on OS's etc etc it was a hard thing to do (esp. outside the US) before the late 80s, cheap commodity hardware let a thousand flowers bloom
