If DG was available to tinker on, to run ROFF, to write small programs for other reasons, to introspect and familiarise yourself with, Then for those students, it became the logical choice. If they ignored the tertiary education market, sold into industry, they could have established a huge loyal fanbase in E.G. Finance and Insurance. Or in the decision support systems in Oil. Or shoe makers inventory control. But if you don't have a cohort of students who recognize your brand, your flavour of UNIX, and you then face these students flexing muscles at purchase time, Instead of "lets buy the upgrade option from DG" you get "why don't we buy Sun, and then get cheap kids to run it" TL;DR DG did not have significant presence in the tertiary education systems I played in (York, Leeds, UCL, UQ) and by my visibility, almost any tertiary education facility I have seen. They didn't feed the beast.
