Drawbacks of P2P and a defense of Signal
Yet another "Matrix isn't mature enough so just give up and use a centralized service" post that completely ignores the fact that XMPP is still alive and kicking.  With multiple independent implementations (both client and server) that all work together pretty decently.We're never ever going to tear ourselves away from this death by centralization if we keep inventing excuses for why we don't use the federated/distributed systems that we already have!Edit:  for those who are interested in using XMPP in 2021, there is a good list of public servers available at https://list.jabber.at/ and a list of clients that support modern OMEMO end-to-end encryption at https://omemo.top/
