You cannot know what kind of government we will have in ten years, nor is it said that your good behavior will be enough to keep you out of trouble. Millions of Jews had done nothing wrong, yet they were persecuted. Moreover, the fact that you have nothing to hide does not fully express what you could do if you had instead: sort of like giving up your right to speak because you have nothing to say.

This seems completely off-topic to me. I never said I have nothing to hide. The Signal client app (i.e. the part that you can audit, compile and run, not the server) provides a lot of privacy already: e2e encryption via the excellent Signal protocol, private profile, private groups, sealed sender. So in terms of metadata, the Signal server never knows what you write, who is in which group, and to whom you are writing. Again, from the client code that you can audit yourself before you run it.

On top of that, leveraging the secure enclaves, the Signal server (tries to) guarantee(s) the private contact discovery (based on the hashes of your contact list). Which means that if you trust the SGX enclave, all that the Signal server knows is your phone number. If you don't trust the enclave, then you can assume that the server got access to your contacts when you did the discovery (i.e. when you installed the app).

That's very, very, very far from saying I have nothing to hide.

Signal introduced closed-source server side code last November. The founder and CEO stepped down from his position this January... End of story to me about Signal

Signal introduced closed-source server side code last November.

What? I'm not aware of that. Source?
