Common knowledge to whom?

Remember, this article talks about Signal which is a widely available app beyond just the USA. Where I come from we have not learned anything about Radio Free or what it has to do with the CIA. I have never heard of it. Same for Moonies. I have no clue what it is and I'm convinced most people in Europe who are of my age have no clue. We all know what Signal is though. So if someone is suggesting conspiracy theories they better provide some references otherwise it reads to me like a sci-fi story.

> Heck, even Wikipedia would do for the basic ties

I mean yes... Wikipedia will do the basics on literally any topic in the world :)
