I'll add another thank you for the detailed, cross-culture (networking) 
life story.

When I worked for a company that sold TCP/IP stacks, a very large 
fraction of our revenue came from Europe, the purported hotbed of OSI.  
As icing, I like that one of my larger customers the ISO IT team...

As Einar Stefferud summarized:  “OSI is a beautiful dream, and TCP/IP 
<https://spectrum.ieee.org/tag/tcp-ip> is living it!”

My own summary was that the OSI community did a superb job of marketing, 
creating a strong demand for open systems, and TCP/IP did a superb job 
of satisfying the demand.
