RFA isn't part of the CIA. It's part of U.S. Agency for Global Media. From Wikipedia:
an independent agency of the United States government which operates various state-run media outlets.[2] It describes its mission, "vital to US national interests", to "inform, engage, and connect people around the world in support of freedom and democracy"[3] and in accordance with the "broad foreign policy objectives of the United States".[4] USAGM supervises Voice of America (VOA), Radio Free Europe/Radio Liberty, Radio y Televisión Martí, Radio Free Asia, and Alhurra TV and Radio Sawa.
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]

Whether that's still true today or not is not something that anyone here is going to agree on.
Why is it so difficult for Americans to believe
Suggesting that "Americans" suffer from a lack of introspection reveals your own biases. 350 million people. 350 million different worldviews.
RFA is still run by the US Government, which is worth considering when talking about the possible biases of RFA... but the NYT article you linked has nothing to do with the current RFA.
The RFA from the 1977 article and the RFA today were separated by 44 years.
Perhaps you're confused because they have the same name.
