I think the disconnect here is that at least for a large part of RFA/RFE's history, simply broadcasting fair and accurate news was effective "propaganda".
Whether that's still true today or not is not something that anyone here is going to agree on.
The "Truth" (or facts presented in a very specific way) is a incredibly effective form of propaganda. You think foreign governments like Chin haven't been using the storming of the United States Capitol as a means to demonstrate the US's weakness or incompetence?
So in your view as one of 350 million, RFA is only(or mainly) set up for providing news to brainwashed Chinese people but not promoting democracy and universal human rights value?
Why is it so difficult for Americans to believe that the US engages in a war of propaganda against countries it labels as “adversaries”? [1]
