Commercial interests tend to progresively degrade the quality of the news if there are no state-funded news channels. They publish more and more unverified "facts", conspiracy theories, tabloid news, AI slop, AI images instead of real news photograpy, intrusive ads, etc.

When there's a news channel funded by the state (instead of ads), most other private news are forced to keep up the quality and they also have the opportunity to call out any bad news and biases published by the state channel. This way no news outlets stray too far from the truth or become unreadable slop. It's better overall.
