It was asked in good faith and I did explain my reasoning for why anonymity and security are different concepts. Have you got a citation for the claim that Signal "uploads entire contact lists" or was this just FUD?
But if you don't believe anonymity is an important component for security, you probably think hashes uploaded and deleted are perfectly secure, too, so we're probably not going to come to any agreement here.
Personally, I do wish they'd decouple from phone numbers and allow users an option not to transmit hashes for their entire contact list. I don't think these are unreasonable features for a messenger that's supposed to be designed for privacy and activism.
