> unless they have it in their phone’s contacts

Lol. Why should they be allowed to associate my phone with my signal handle even then. If i want them to know I'll tell them.

> a new privacy setting to limit who can find you by your phone number on Signal

Double lol. Limit is not disable.

How about an option to "do not give my phone number to anyone, no matter what reason to pass it around you make up this week"?

And the obvious next step: do not get my phone number period. But that has been discussed before.

As far as I can tell, "limit" will soon mean "disable". They just can't flip that switch yet given that legacy clients will not know what to do about "numberless contacts".

> do not get my phone number period

I'd also like that, but they apparently use phone numbers as a primary key for account recovery and identification (e.g. on a new device without the old one present), so that's probably very hard to change architecturally.

There are some interesting concepts of "identityless messengers", but this is inherently hard to do on mobile – at least the platform operator will always know which identities are clustered together on a given device if you want efficient push notification delivery over APNs/FCM.

Like... icq... yahoo messenger... old skype... ?

And even some modern mobile chat apps i think.

These definitely all had a stable identity (ICQ number etc.)

What I mean is having an ad-hoc identifier per contact/group chat which doesn’t allow your various contacts to correlate that you are the same person.
