I’ve been using SimpleX for a small circle of friends and it has been pretty easy to use. I am surprised it has not seen wider adoption. Writing scripts for it is also straightforward.
And if they don't need to, and it just works as a regular encrypted messenger: Why should somebody use this over any of the many alternatives?
Other than that, its "advantages" page looks highly disingenuous, e.g. by describing Signal as "Possibility of MITM: Yes", but itself as "No - Secure", with a footnote of "Verify security code to mitigate attack on out-of-band channel". How is that different from verifying a Signal verification code!?
- no phone number
- no account
- p2p via onion routing and public relay servers
- public and private file sharing systems via XFTP
All owned by two entities. I would buy their claim if they just used Tor or i2p as a transport layer, which are not that easy to control like a relay server farm owned by a single entity.
