Central authorities have refused to interop even on text messaging, up to the point where text messaging was possible between apps 10 years ago but has been made impossible. We went from Pidgin to 10 messaging apps that don't interop basic text. The incentives on central authorities is always to abuse their power. That's how we got Facebook. Blockchain is not a promise of an utopia, but the incentives are radically different. And in some ways, "central authorities with interop" is a description of blockchain where not everyone is running a full node.
