I'm gonna be honest. I chose a random article by JWZ and read it. The only thing they are talking about is the contact discovery system. If they don't want contacts to be uploaded (encrypted) then simply don't give signal the permission. And that the author moves to facebook messenger because there
at least the privacy failings are obvious
just shows how the author isn't even interested in secure and private messaging but only in defamig signal
No i think you misunderstood. Local backups (as we have them now) will (most likely) stay.
