    Sure, they exist, but Signal is against them. Look into what they did against LibreSignal.

    Now part of the problem with LibreSignal was the trademark violation of using the name Signal. But Moxie is clearly against any third party using their servers, as we can see in this comment: https://github.com/LibreSignal/LibreSignal/issues/37#issueco...

    IMO that's an unforgivable stance towards third party clients.

    Signal is openly against third party clients:

    Also how easy is it to run a custom Signal server?

    Moxie (Signal's founder) has thrown fits in the past over the existence of third-party clients using their servers: https://github.com/libresignal/libresignal/issues/37#issueco...

    I push back when anyone recommends Signal because they are fundamentally not an open network.

    OWS has historically been hostile to third party implementations outside of their clients. There are multiple unofficial options but the only one I've been looking at is the bridge with matrix, though setting up a matrix server just for this is likely overkill.

    I have to say that I find him fascinating too, but there are a few things that raise my suspicion, but of course do not convict him of anything:

    The way he is attacking this alternative Signal client and rules out interoperability:

    https://github.com/LibreSignal/LibreSignal/issues/37#issueco...

    Signal was a word before he decided to turn it into a brand.

    The signal server source code repo was not updated for a year. Communication intransparent.

    I am not even against crypto integration, but I found the choice of MobileCoin odd. Instead of integrating an existing privacy coin or working with the community, he decided to integrate MOB and to be one of their "advisors":

  • Snap Store administrators removed signal-desktop from Ubuntu Snap

    Is that so surprising? Signal had always a hostile attitude to alternative clients. They have this weird disconnect of the new CEO saying they want to be available to as many people as possible and be a fully commited FOSS app, and then have no version on F-Droid (while Telegram has!) and actively fight alternative clients (see https://github.com/LibreSignal/LibreSignal/issues/37#issueco...)

    Because of this hostility Signal is not a trustworthy organization at all.
