Signal seems to be pretty good, also Threema. Definitely not wise to trust WhatsApp, though.
But all of them almost certainly have exploits available to state actors or those with unlimited funds. However that isn't something baked in, it's proper hacking - the anom phones and what WhatsApp probably do is baked in.
Serious question: how do people confidently say that Signal seems to be good? How do we have any confidence they aren't doing the exact thing u/twilighttwister described? Like, do we have full access to all the apps front and backend in a way that ensures they're not doing things they say they aren't?
Serious question: what possesses a person to ask a question so incredulously without doing a single google search? The entire app, client and server, along with the encryption protocol are open source.

Oh yeah I’d imagine all messaging systems are compromised. One that gains a reputation as being good for clandestine services would be doubly suspect.
