At the time VMS was conceived, Unix was a university
product, used for
teaching and research, not for heavy production work.
Err, not quite. In the mid-70's, the PWB system at Bell:

was being used by a community of about 1K programmers doing development of
software for various Bell commercial projects.
Yes, not accounting systems, but not "teaching and research", either. And it
was definitely production: see the uptime statistics, etc, in the BSTJ
article that describes it.
