Fwiw, the FBI use Signal regularly, and it's approved for some specific use cases. Don't ask how I know ;)
There are ways to ascertain how and when a person is using their device by analyzing Signal's metadata, then build a predictive model based on months of daily usage to infer when they're most likely about to pick up their phone.
Delta Chat is years behind Signal's protections, and its claims of "zero metadata" are straight up lies. SimpleX has at least four remote execution zero days that I'm aware of, all relating to media processing. I told Evgeny to make the blur effect actually hash the image instead of acting like an overlay, but I was repeatedly ignored before being set as an "observer" role in the SimpleX Public Group.
