From what I can read, there is no mention of being able to register a new account without a phone number. It's all about not giving your phone number to anyone else (Signal of course already has it, and automatically ties it to your username).
If new accounts can be created without requiring a phone number, this is actual privacy improvement. If not, it's PR bullshit.
Has anyone tested this?
@andymouse @evacide "you will still need a phone number to sign up for Signal"
This is just for contacts
