Maybe IBM can offer uni's a version of zPDT that can run on multi-socket
rack servers so they don't have to subsidize hardware, only software.
I'm sure that would be more than capable for running z/OS with more than
acceptable performance.

Which is better than, say, ~5 years ago.
It is my faded-memory impression that it was, as Timothy pointed
out, DEC's aggressive push of very low-cost and free "stuff" into
universities that both permitted and accelerated the rise of *ix
and also contributed to the decline of IBM mainframes on campus
(though that was not the only reason).
My recollection is that DEC didn't really want it that way. DEC would have
very much preferred if VMS and/or TOPS-10/20 got more popular in academia.
Sure, DEC was happier if BSD UNIX ran on their PDP or VAX hardware rather
than somebody else's hardware, but in hindsight that wasn't enough.
It's impossible to re-run history, but I suspect that if DEC didn't provide
subsidized hardware to run AT&T's/BSD's operating system then there'd just
be some other subsidized hardware performing the same role. It would have
been something of early 1970s vintage that competed with the PDP-11. Maybe
something from CDC, Data General, or Honeywell/Prime. There was also a
fortuitous bit of DARPA funding aimed at Berkeley that helped UNIX at a
critical stage in its evolution.
