The problem is not that people are lazy; the problem with open systems is that they are much harder to moderate and people want effective moderation. Usenet was open, decentralized, and wound up dying because there were too many problems with moderation and white supremacists etc. would show up and flood NGs with their nonsense.

There are also legal issues that kill decentralized/user-controlled systems. Copyright and child abuse are the most prominent, along with terrorism and drug trafficking. Who gets sued or prosecuted when the system is open, decentralized, and user-controlled? The users, and that's why peer-to-peer filesharing died, why so few people are willing to host a Tor exit node, etc. Before talking about banning centralized systems we need to talk about updating the legal system so that it does not force centralization, which is a much bigger project and much harder to get right.

The moderation problem wouldn't have been hard to solve on USENET, it's just that nobody wanted to do it. It could work exactly like moderation does on Mastodon, where each admin is responsible for the content on their server(s). There isn't a technical reason why you couldn't do that, and even give individuals moderation rights on specific lists. Of course, this only affects your particular news server, but it lets the white supremacist post their insane ramblings over on Giganews, while you and I read less toxic version of the thread over on Cozy News. If you don't like the moderation on your server, go find another one.

> that's why peer-to-peer filesharing died

p2p file sharing is still huge, though. Most people just put their seedboxes behind a VPN to avoid getting DMCA notices.
