> fully open source including the server side But, and maybe I'm stating the obvious but it is a critical difference, open source is nice but much inferior to open interoperable standards. Signal-the-company does not allow any clients other than their proprietary compiled client (I believe they sort of tolerate some, but not supported). So while in theory I could use the open source software to run my parallel signal-protocol network, it won't interoperate with the one run by Signal-the-company which is where most people are. So, not actually useful. Contrast this with email which is an open standard. I can run any SMTP server I like and any MUA I like (or even write my own for one or both), and interoperate with the whole universe of people who use email.
