I had no idea that there were Signal clones that used the same protocol and then did, well whatever they want with the info. Notably they could be archiving in plaintext all your beautifully encrypted and secure messages. I get (sort of) why Signal might allow this but I also think it has the potential to be massively brand damaging. They could require authentication in a way that stopped this.
