• Did Signal devs openly refuse making use of that? Honestly I think it’s understandable.

    They are marketing the app as a very-very secure messaging app, but all the security with no exception would go out of the window if you were to send or receive a message from messenger.
    And they are also making it very-very easy, because - as bad as it sounds - a lot of people don’t understand what is encryption, what are platforms, and they don’t even care to get to know about it, and because of that, these users would have no idea that their chats with messenger users is not encrypted.

    • Well I didn’t found anything regarding this on GitHub. And to be honest I only find some german language articles about this speaking of an announcement that signal don’t likes the idea enabling Chats with WhatsApp… so I assume this comes from Twitter.

      Like I said turn it of by default so that only people who activity made the decision can be chat with WhatsApp. Also showing a hint in the chat that this account is not on a signal server should also not be that hard to implement.
