> It's a fenced ecosystem which claims to establish a secure communication but does not. Your concern extends for all systems that require centralisation. Possibly one example of a chat client which addresses the concerns you raise is Ricochet [1]. Your Ricochet messaging client instance acts as a Tor hidden service. Your add contacts by their ricochet ID which is derived from an onion address. There is no central server / service involved. Everything is direct p2p between your messaging client and your peers. The source code has been audited by NCC group [2]. It's limited - text only, no attachments, no voice. If your threat model includes adversaries such as nation states, then this is perhaps the tool to use for simple text messaging.
