"Accurate" means that an institution is not actively trying to mislead, and takes steps to correct factual errors when they occur. All traditional news media in healthy democracies do this. They distinguish clearly between reporting facts and opinions.

"Objective truth is unattainable, so we shouldn't even try" is overly pessimistic and does not reflect reality. Opinions are not facts, and the truth is not an opinion. The truth is often complicated, and a healthy media landscape contains all the relevant perspectives, but none should get away with misrepresenting the facts. You are saying that truth does not exist, while certain organizations and actors are actively doing their best to get away with lying to your face.

It has nothing to do with an "official" narrative - there is none. It is objective truth that RT is a state organization that exists in order to manipulate and lie to Western audiences.
