This is sort of like arguing cutlery is a military enterprise. Like yes, that’s where knives came from. But that’s disconnected enough from modern design, governance and other fundamental concerns as to be irrelevant. The internet—and less ambiguously, the World Wide Web—are more commercial than military.
Source? Not doubting. But I have a friend who was buying airline tickets through CompuServe in the late 80s/early 90s.
