I would like decentralization (mostly for resilience in case of natural and human made disasters if anything), but for the control I am not sure it is better. Someone has to make a choice of what is shown. Someone has to moderate things. And I am not even sure who is the best to do that - am I capable to decide a good balance between in-bubble and out-of-bubble content; or decide about the difference between hate-speech and free-speech ? Who can I trust to do that? Would a communist/libertarian/etc. be better than an insecure wannabe dictator?
