I'm curious what country you're from to have that point of view. In the US the public radio is extremely clearly not a state sanctioned propaganda; some of the corresponding private news corps are much more.
I live in the UK, and the BBC is definitely propaganda.
I also agree with you that private broadcasters can definitely be worse.
OTOH, it's a vicious circle: you cannot fix society without fixing propaganda, and if the propaganda is any good, you cannot fix propaganda without fixing society (most people will lend an ear to it, believe it, parrot it, support it, work for it, etc.)... so we just have to learn to live with it :/
