"How to Use Signal Without Giving Out Your Phone Number"

@caligin that won't always work. In the EU you can't get a legal burner SIM. Even if you did you would sill need a separate device to not have your device ID attached to the number. Similarly VOIP services require verification before creating an account - using a heavily regulated identifier like a phone number in the first place is game over.
@bugshiv good to know, I actually have no idea how device ids work so didn't think about it
