> ISPs are a common carrier and never really moderated the content of newsgroups on usenet.
Strictly speaking that’s not entirely true.
1. They could choose which newsgroups to provide access to as part of their USENET access service.
2. USENET or a modern-day like-service as a separate billable item would not necessarily be subject to the same common carrier provisions that broadband service providers were subject to when they were regulated under Title II of the 1934 Communications Act.
3. This rule was also repealed under the Trump administration and broadband service providers are once again regulated under Title I, which is to say they are not classified as common carriers. Even if it hadn’t been or if they were to be reclassified under Title II, see point 2. I did try to see if this did change under the Biden administration but I have not heard of such a change nor could I find one.
4. ISPs previously did not have the same incentive structure, and were dealing with a different market and legal environment prior to 2002. The truth is, USENET at the scale of Reddit could not exist without good moderation. It would be untenable for all the reasons unmoderated forums are untenable, and also too unappealing to develop a Reddit-sized mass. The mods, for all the issues with Reddit’s mod community, are what make Reddit possible to continue to exist. You would need similar for any Internet social forum of a similar size, scope and user base and if that’s not the goal, plenty of niche forums already exist that you don’t need to get through your ISP.
> I'm billed monthly for internet access and have had this arrangement with multiple companies over the last 30 years. That bill used to include a ISP email account and usenet access. Now it doesn't.
Perhaps you misunderstood me. I don’t have an issue with the billing arrangements I have with my ISP. I have an issue with the idea of getting billed for non-internet access services (read: content) through my ISP as a means of paying for them. In an age of pervasive payment tech like Apple Pay, I want a direct billing relationship with my service providers, not a stack of line items on my internet bill. Put another way, I’m saying it is simply an unappealing arrangement when there are superior alternatives.
I do still have the ISP-provided email address though, completely unused for the last 15 years and if they ever billed me separately for it, it would be terminated instantly.
