> It's that everyone who uses Signal already has a local contact list keyed on phone numbers ... Well, that's precisely why I don't use Signal. In that I don't use smartphones. I could probably run Signal in an Android VM. But I have no way to get a phone number that's both adequately anonymous and adequately secure. Or at least, I don't yet know how to do that. Burner phones are too readily located, and hosted SIMs are too insecure. Android x86 VMs now have functional virtual WiFi interfaces. But I'm not aware of a virtual cellular network implementation, which could theoretically (I imagine) allow virtual SIMs. That would be very cool. Or maybe it's doable with VoIP?
