the ideological underpinnings are what allowed Linux to overtake BSD during "the troubles" of the early 90s As I understood it, also to a degree witnessing it as it happened, this lawsuit spiked BSD at the critical period: https://en.wikipedia.org/wiki/UNIX_System_Laboratories,_Inc._v._Berkeley_Software_Design,_Inc https://en.wikipedia.org/wiki/UNIX_System_Laboratories,_Inc..... It certainly took Linux a long time to get in the ballpark of quality that BSD started out with at the gate, including the standard TCP/IP stack most everyone used, including Microsoft (initially, at least).
