An interesting article I saw (from 2019) describing the potential intrinsic tendency for decentralized platforms to collapse into de facto centralized ones. Author identifies two extremes, "information dictatorship" and "information anarchy", and the flaws of each, as well as a third option "information democracy" to try and capture the best aspects of decentralization while eschewing the worst. Someone said the link is broken so here it is: https://rosenzweig.io/blog/the-federation-fallacy.html
