The cost to ISPs was mostly in the binaries groups, and some usenet servers were set up as a paid service for this purpose when ISPs started dropping the binaries groups. I don't blame the ISPs for this. At the time, you could be an ISP with what is essentially a low-end home Internet connection now, but it cost thousands per month. What started the downfall of Usenet was Eternal September when AOL let their hoi polloi access the Big Boy Internet. The "Me-tooer" phenomenon was particularly irritating.
