I don't think it's a technical problem and I think the problems the articel points out are social and economic problems. I once started to design a protocol that could be used to build a decentralized social network. (FOSP https://github.com/maufl/fosp-specification) However, I now think that a peer-to-peer solution would be better, even if it is technically more challenging, as it would not require anybody to run a server and untilize the resources the users already pay for (storage, network connection).
