Do you think Whatsapp is actually encrypted and isn’t a tool to get more information from its users because Meta pinky promised? Closed source piece of garbage.
Open Whisper did the actual message algorithm, and I understand it’s open source. It could be copying your messages at the endpoint, I guess, but nobody has caught it doing that on wireshark to date.
I do trust Open Whisper and their open source project as well. I also trust Meta to do everything possible to collect even the slightest bit of data possible. Plus as Whatsapp is completely proprietary we don’t know how the solution from Open Whisper was integrated. Why not open source it like Signal does?
