You make a number of good points. A few comments:

That last part was really a big factor, one not to be understated. That
penetration led to production of a whole generation of people who i) were
familiar with Unix, and ii) liked it, and were not about to put up with the
OS's being turned out by various vendors.

'Embedded systems'. The number of PDP-11's running timesharing was a small
share of the total number, I expect.

Very true. My jaw basically hit the floor when I first saw (ca. '75) what Unix
was like. People who didn't live through that transition can't _really_ grok
it, any more than my kids can really fully grok a world without mobile
phones. It wasn't as powerful as Multics, but I was completely blown away that
anyone could get that much capability into a PDP-11 OS.
