Cisco was a rip off of The Stanford Blue Box. AFAIK the deans of the biz school and CS school founded Cisco with tech created by Stanford and were almost sued. Stanford decided that it wasn’t worth the potential bad press to be sueing faculty.
We may be approaching a world where all critical infrastructure must be open hardware and software, or face a Balkenizd patchwork of suppliers local to each market.
(Not a Cisco or Huawei fan myself.)
