and dismantling “secure messaging apps” for drug gangs

Which are usually not secure.

Of what I've heard, gangsters seem to be amazingly naive in the sense of really acting along the movie model of "finding that smart nerd guy who'll make the obscurest thing in existence". They don't know the thumb rules of "don't roll out your own crypto" and "security through obscurity" being bad and that math doesn't pick sides.

So - they look at respected solutions, like Signal or something else, and think that they are smarter and to be safer, they'll find someone real, and they do. And the person or group or company they find is usually employed with some secret service.

Then the "directed by Robert B Weide" caps appear.

In some sense that's similar to what Israel did to Hezbollah with pagers.
