Which is honestly not really all that surprising. This page was likely written exactly because of the 'era of widespread availability of software and copyright wars' - e.g. the statement: "One of the fun examples among all the copyright fuss" combined with the edit dates (90,93) seem to me to indicate this was written exactly as a response to the UCB vs USL suit.. https://en.wikipedia.org/wiki/UNIX_System_Laboratories,_Inc._v._Berkeley_Software_Design,_Inc https://en.wikipedia.org/wiki/UNIX_System_Laboratories,_Inc..... as well as the 'unix wars' https://en.wikipedia.org/wiki/Unix_wars https://en.wikipedia.org/wiki/Unix_wars
