Not sure why the phone number thing bothers people -- having a phone at all in the first place means you are easily tracked. What Signal (and any encryption system, really) does is try to prevent in-transit interception and surveillance of the actual data content. It can't hide the metadata associated with a layer well above the application layer. Openwhisper can be picked up at the firewall level, but then so can Tor and VPN spinups, and all of these things are metadata that make you score more interesting to the mass-data-scoop algorithms. If you don't want to be easily geo-locationally tracked, don't use a device with a cellular modem, full stop.
What Signal (or any other E2E encrypted messaging system) does is give people the ability to communicate with each other privately. People can still see that they are talking and are trying to hide what they are saying. Yeah, that makes those people targets in some countries, but it also greatly increases the cost in manpower and resources needed to peek into those communications. Now you're looking at burning 0days to install APTs and sending human resources to deal with individuals when this could previously be handled on a global level en masse with some fiber splitters and a big ol' datacenter. If enough people use it can have a disruptive effect on mass surveillance and state control. -Ryan McGinnis https://bigstormpicture.com PGP: 5C73 8727 EE58 786A 777C 4F1D B5AA 3FA3 486E D7AD Sent with ProtonMail ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Tuesday, July 2, 2019 10:20 PM, Mirimir via Gnupg-users <gnupg-users@gnupg.org> wrote: > On 07/02/2019 05:18 AM, Robert J.
