" There runs a direct line from the 1-900 phone industry to the internet adult industry"

the internet adult industry is not the same as the internet. And if you;re trying to say the internet was developed for the sake of the internet adult industry, you're sounding circular.

I never made that claim and I'm fairly familiar with the development of the early internet, I was hanging around a lot at CWI/NikHef in the 80's and early 90's.
