@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.
