There's a "Signal deanonymized" thing going around:

Stay calm. Deep breaths.
@rysiek I don't think people should be using #Signal, besides this problem, it is a centralized service which means it is vulnerable to enshitification and it requires phone numbers to register which sucks a hell lot
I use #DeltaChat, decentralized, anonymous, no data required for registration, and it doesn't have this deanonymization attack problem
@adbenitez I would love people to use decentralized tools. I did a talk/rant about things that annoy me in Signal at MCH2022. This included the phone numbers thing:

That does not mean that Signal has no value. If somebody is already using Signal, they're in a way, way better position, than if using any of the corporate apps (like WhatsApp), or any of the shady crap (like Telegram).
It's a question of harm reduction.
@rysiek @adbenitez Yep it's a better alternative to WhatsApp
