There’s a ton of compelling evidence that VOA is not propaganda.
I linked a bunch of media bias and fact checkers earlier: in case you missed them, heretheyareagain. So… yeah, it seems from the available evidence it has in fact changed in a hundred years.
Unless, of course, you think that every media fact checker is wrong. In which case, again, it must be easy to provide some kind of source or evidence that either they are, or that VOA is in fact merely propaganda.
