alt Hacker NewsYou can have multiple instances of signal on a mobile device, and you can use VoiP or eSIMs to register. Signal with an online persona revealing no identifying information, registered to a cash purchased eSIM on an ungoogled android is as good as your getting. Why do you think so many jurisdictions are trying to ban both GrapheneOS and Signal.

You can do all of that but you shouldn't have to when using a privacy-focused messenger, and most people won't so they'll be exposed and suffer the consequences if they use Signal expecting a certain level of privacy (and pseudo-anonymity).
It's a terrible anti-feature and the only reason they're not being punished for it is because there aren't many alternatives to pick from.
That's privacy for someone who cares deeply and will get it somehow no matter what, not default zero-effort privacy for the ignorant. (Which WhatsApp does pretty well for example.)
Of course it's revealing information. If I know that two users that are identified by their phone numbers are talking to each other every day, this is a clear connection you can exploit. Metadata is only useless if you have no imagination.
In europe you need identification to buy a sim or esim.
