Mostly life experience, I would say. Through experience one knows that managing opinions of other people is part of keeping one's position in society (e.g. being the big boss). One also experiences that these opinions others hold are based on the messages (or news) they receive. Therefore controlling the press is important to maintain power. Therefore nothing is more pain in the ass to a government than the reporters of differently typed governments. Especially reporterts from directly declared enemies and from governments that are much better at controlling the news than oneself. Think about the guy in the office who exploits people all the time but for some reason the majority always seems to like him. Now think about him badmouthing you in front of you and others. Wouldn't you feel forced to react somehow?
