Yeah, in 1988 the Internet appeared like a research network that connected universities. No money was directly at stake and the systems harmed didn't appear critical. Related to what Thomas says above, part of the response to the incident was to partition the Internet for a few days [2] - I don't know if such a thing would be possible now.
But looking into the specifics again after all these years [1], I read:
"The N.S.A. wanted to clamp a lid on as much of the affair as it could. Within days, the agency’s National Computer Security Center, where the elder Morris worked, asked Purdue University to remove from its computers information about the internal workings of the virus."
and that CERT at CMU was one response to the incident [2].
So there is a whiff of the incident being steered away from public prosecution and towards setting up security institutions.
Robert Morris did get a felony conviction, three years probation, and a $10K fine. As for hn users, aside from pg, Cliff Stoll has a minor role in the story.
