I work in the adult industry as a software developer. This article is very, very accurate. And that statistic you have problems with is also true. In 2000 most people were downloading base64-encoded porn from newsgroups or JPGs from modem-based BBSes that hosted multiple adult CDs. Danni's Hard Drive was one of the first adult sites on the web. It got so popular that it created a payment processor called DHD Media, which mostly handles adult membership payments. But like an aging porn star, they're pretty useless now.
