Do you think they’re lying to authorities when they get a search warrant? https://signal.org/bigbrother/santa-clara-county/ That would be quite a big deal, and someone will be going to jail if you’re right.
All they have is your phone number, the date the account was created, and the last time it connected to the service. Yes, that represents a vulnerability, but you;re just casting aspersions that the whole thing is compromised.
Maybe there is some super secret NSA back door that Signal engineers aren’t even aware of. But it’s at least pretty clear that the local fascist authorities aren’t getting that info even with a warrant.
But you still post in lemmy.ml/privacy?
