Centralization isn't just about the network architecture. A decentralized system wouldn't have a single organization or app whose neck can be strangled by the state or Apple/Google. I acknowledge that the current app store gatekeeper model makes this difficult to implement or even imagine. I also acknowledge that this is difficult to reconcile with the Signal Foundation's implicit 'institutional imperative' to continue existing as a central supporting party. I understand the "ecosystem is moving" usability / anti-ossification argument for centralization; it's just that the cost of centralization, when operating under the authority of someone who opposes privacy, is privacy.
