And because of that transparency, it actually has lead to, among other things, significantly better media literacy. In the west people take the news headlines at face value because we have free press, so therefore whatever you read is probably true. In reality, its just as obscured, censored, and biased towards the bourgeoisie as socialist state owned media is to their state. However in such societies, people know that going into it and therefore think more critically about what they read. Where in the west we see people believing every little thing they see on facebook, people in socialist states are more incentivized to go out and actually educate themselves because they are under no illusions of an infallible free press.
Both systems are equally as repressive (granted towards different parts of society), yet the outcome is fairly different.
I suppose 'capacity for repression' is a better way to say it. That was supposed to be more demonstrative of the nature of media in class struggle (and how it doesnt change no matter who controls it) instead of calling socialist systems repressive
