On its 10th anniversary, Signal’s president wants to remind you that the world’s most secure communications platform is a nonprofit. It’s free. It doesn’t track you or serve you ads. It pays its engineers very well. And it’s a go-to app for hundreds of millions of people.
Signal’s hostility to 3rd party clients is a huge red flag.
Can you further explain? A red flag to open-source, federation and such, can’t disagree. But to privacy and security? I’m not convinced.
Third party clients are the best way to verify that the protocol works as advertised.
If you backdoored your client, then you will naturally oppose anyone else who develops a client.
