| You're forgetting spam. Spam destroyed all those first generation federated systems. IRC survived because it was too niche for spammers to target much but spam is the primary thing that killed Usenet and email as a truly open system. The closed systems were better able to fight spam because they could easily ban people and IPs. On a deeper level spam, "brattish" commercial sites, etc. all come from when money got involved. The old Internet was mostly noncommercial. Money changes everything. Even on the new sites I saw a massive shift when e.g. it became possible to monetize YouTube videos. All the sudden everything became about engagement and controversy and got big and divisive and dumb and flashy. Ultimately we must adapt or perish. There is no going back. I think all new systems must be designed with the trial by fire of spam and other profit motivated attacks in mind from the start. |
Usenet on the other hand required cooperation from all providers. Actually I blame Google for killing Usenet. They used Microsoft's EEE (Embrace, Extend, Extinguish). They acquired DejaNews, renamed it to Google Groups, provided a gateway that allowed everyone to use Usenet. This introduced a lot of spam to the network, but whenever someone reported it, they did nothing. Eventually they introduced their internal groups, and shifted search in a way that it got hard to use Google Groups for searching Usenet posts.
They did similar thing with XMPP (Jabber). When they introduced Google Talk, their service was interconnected with the other XMPP servers. Once it got popular they discontinued it and introduced Hangouts (then later iterations) Hangouts was still connected people could see each other being present people on Hangouts could message anyone, but people on other XMPP couldn't message people on Hangouts. It didn't even show an error. This made many users switch to Hangouts to continue taking with their friends.
They attempted to do the same thing with email, but were less successful (since many big companies are also providing the service), this was done through introducing various anti spam measures. You now have to jump through various hoops (SPF, DKIM, RBAC) to have your service still reach Google uses. It didn't matter that I used the same IP and domain for 15 years never had spam sent from it, but suddenly my emails started being silently classified as spam without any warning.
