Hi there, engineer on the Signal Android app here. Just an FYI that the notifications are generated on the receiving client by detecting that one of their contacts newly showed up as a registered user -- they're not "sent out" by you when you register or anything. Also, these notifications have defaulted to being disabled for the last 1.5 years or so. So only people who go into their settings to manually turn them on should be seeing them at this point. That said, the complaint around this is usually that people don't want others to know that they use Signal. And unfortunately there was no way to _really_ do that (until now), because if you open your chat list, you'll see all of your registered contacts. But in the 7.0 release, we added the ability to hide yourself from being discoverable by phone number at all. So for people who don't want anyone else to know that their phone number is registered with Signal, they now have that option. |

How can a privacy oriented company not see the privacy implication of this? Sometimes, you want to be forgotten by some people, and Signal is telling them you are still there and active on that number. I remember reading a story about someone getting into real trouble for that.
Without "usernames", the proper way to handle it would have been to not let anyone know you are on signal when they look up your number. To get into contact, send a message, then the recipient will receive a notification with the message and an option to rely. If the recipient doesn't respond, from the sender point of view, it should be as if the account didn't exist.
