Starting into the article, I got the impression that it was heading for a “centralization ultimately better” argument, so I’m glad it concludes on decentralization and federation. There are no issues that exist on federated and distributed channels as individual nodes that don’t also exist on centralized ones, differences only emerge when you try to treat or exercise control over distributed systems as a group. Facebook is completely centralized, but they still have to deal with third party content making its way onto their platform via bots, API posts, integrations, ads, etc. The big difference is that with a centralized platform, you have a Single Point of Failure, and that’s bad all-around. There is literally no advantage to a centralized platform that I can think of (though I’m sure that people less opposed to authority/ hierarchy would disagree).
