For open source messengers, you can check whether they actually encrypt your messages and whether the server has access to your encryption keys but what about WhatsApp? Since it’s not open source, you can’t be sure that the encryption keys aren’t sent to the server, right? Has there been a case where a government was able to access WhatsApp chats without reading them from the phone itself?
Fair enough, I guess. Still, in my honest opinion, it’s not worth it. They’ve already long since betrayed my trust, so they could say the sky is blue and I still wouldn’t trust them. Lol.
