"Propaganda" is an underused term. The propaganda industry renamed itself as the "public relations" industry (Bernays quite literally coined the term.) After that "propaganda" meant "public relations that I disapprove of i.e. communists."

The overused term is "unbiased" which doesn't mean anything. The closest meaningful word to it is "disinterested" which means that the person conveying the information doesn't particularly care about it.
