    There is threema, a Swiss messenger that gained some popularity earlier since they had end to end encryption before whatsapp.

    Unfortunately the source code is not open (even though they do get annual audits with public reports), and the client costs 3 EUR or something (once).

      Yeah, but Threema has basically no momentum behind it at all at this point.
      I’m putting my social capital behind the option that currently stands the most chance of beating out Whatsapp

        That’s just the client, the server architecture is what really matters.

        FYI, while Threema front-end clients (apps) are open-source (and offer reproducible builds, which is surprisingly uncommon in open-source land), the server component, though supposedly audited, remains closed-source.

        EDIT: for comparison, the Signal server code is mostly open source, but things like the spam filter are closed.

          Thanks.

          And I didn’t know Signal had spam filters. It makes sense to not make that open source.

          In my circle of 20 there has only been one instance of spam over several years. 3 of us got the same message.
