I wasn’t saying the US doesn’t spy on private messages, I was saying Signal is open source so it would be hard to hide a back door. So I don’t see how any other E2E encrypted messages could be more secret then Signal. I guess obfuscating the messaging servers.
The sophistication of data surveillance and data gathering makes the content of the message rather meaningless in my view.
That’s a fair point but I don’t know if there’s any other good solution to that.
I think finding novel ways to communicate with a specific person and not be monitored is easy. The difficulty is opening a new line of communication on an already monitored one, communicating to new people, and one of those new people not blabbing.
After all, if you play on a private Minecraft server and spell out text with dirt blocks, I don’t think anyone’s going to bother writing code to analyze your Minecraft network traffic.
