There is no way in hell this guy worked for FBI or any US intelligence agencies. Intelligence folks barely talk about what they do, much less scream about it. He is a seriously deluded phony.
That was true when there were professionals working in the IC, you’d be surprised by the whack jobs that work in it now. The military is getting to be the same way, sometimes when I’m working on a navy ship I just look around and say, there’s just no way we can win with the shitty training these kids get. If our navy gets in a battle and loses to the Chinese, it will not be because of the hardware or the technology or the ship, that stuff is the best in the world; it will be because the crews are not properly trained how to fight their ship, how to do damage control, but man do they know their micro-aggressions and all that other stupid woke crap.
I don’t think serious hackers brag, either.
