Private =/= anonymous
Signal is amazing
Anonymity is good but that's not the biggest problem with Signal's reliance on phone numbers. Phone numbers are just not secure and not designed to be authentication credentials. Phone services are vulnerable to a large number of exploits and that's never going to change. Signal has a number of mitigations to try preventing those exploits from hitting people but that's a bandage at best. Reliance on phone numbers is a gigantic weak point in Signal's privacy and security.
