The problem, I feel, is that both centralisation and decentralisation are a danger to democracy. Centralisation because it enables elites within the tech/media/state to conspire together to wield much more power within a "democracy" than such a system needs to run equitably. Decentralisation because it allows foreign actors to more-or-less do military manouvres within social media in order to cause particular outcomes (e.g. polarisation, destabilisation, regime change, forming opinions within a population that are economically beneficial to the attacking country, etc).
