Exposing my DID and then farming my contact database so it can tell me when people I know sign up for #Signal (and Vice Verse - it tells people who have your DID in their contact database when you're a signal user too) is an egregious invasion of my privacy!!!
I do understand that Signal has been working to get rid of the #DID requirement, and received notification of such a day or so ago, but there's still a bad taste left in my mouth for encroachments.
