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.
If you backdoored your client, then you will naturally oppose anyone else who develops a client.
Third party clients are the best way to verify that the protocol works as advertised.
