Not the author, but to me the main benefit of decentralisation will always be the stability of independence from organisations. If any aspect is centralised, you are dependent on the provider of that service. What if they go out of business, what if the EU make encrypted chat illegal, what if they get coerced by the state to hand over information? An entire class of security issues disappear when you are not dependent on a third party, particularly one that with be subject to state regulation and interference.
