Mh, nntp news are decentralized and no one control the entire network, email are similar in that sense. On crypto GNUPG works in a fairly decentralized concept because yes we have keyservers but they are no single body and we can also build "sub-network" of trust as we want. On cryptocurrencies that seems IMO the "real" topic of the article IMO they are not a "free new form of currency" but a test by some bigs of IT that think they are big enough to substitute with their infrastructure the actual banking system. Of course cryptocurrencies are generally free software but due to poor scalability of blockchain operations and it's ever-grown size and the substantial need of connection and hw to operate they are de-facto a controllable ecosystem. And actual hw and firmware's trend is direct in a really dangerous direction. IMO the problem is not much centralized vs decentralized or distributed but a matter of "design mind", today most people are unable to think free by design solution, being born in an unfree world where web tech are so "affordable&effective" that seems to work like magic.
