Delta chat is also less secure than Signal because it runs on standard email servers, which inherently leak more tracking metadata (like sender and recipient addresses) and lack Signal’s advanced privacy features like Perfect Forward Secrecy.
These addresses are randomly generated addresses which you can rotate whenever you want which seems better than giving signal your phone number or payment information
Signals reliance on phone numbers is my biggest problem with it. I don’t understand why they can’t move away from them entirely.
You can already today share a username instead of a phone number, this is just extra for signup.
Still need a phone number to sign up though, or pay.
Just use a secondary number not connected to you. It’s not that difficult.
