"we" paid ISP's ... which in turn, paid for infrastructure. Some of "we" pay cable providers for internet service, which in turn paid for (in my case) fiber-to-the-curb. Advertising basically supported social media, search engines, etc.

No. The internet was not a commercial enterprise, it was first and foremost a military enterprise, just like GPS.

> it was first and foremost a military enterprise, just like GPS

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.

This is moving the goalposts. The commenter above is talking about the enthusiast-populated internet of the late 80s/early 90s, at which point it still wasn't even clear if it was legal to use the internet for commercial purposes. If all you mean to say is that the internet is currently commercialized, yes, that is obviously true, in much the same way that a disgusting ball of decomposing fungus may have once been an apple.

Source? Not doubting. But I have a friend who was buying airline tickets through CompuServe in the late 80s/early 90s.

Compuserve was NOT the internet. Compuserve / Prodigy / GEnie were early versions of Facebook. They also inter-operated (email) for some period of time. IIRC.

An important distinction, although I do remember AOL making a strong go at "branding" the internet by the late 90s.
