> all produced information is unavoidably narrativization

This is a future possibility but it has not yet come to pass, and we can still avoid it. We are not yet adrift in a sea of epistemological relativism where everyone has their own truth, and no objective truth can be discerned. We don't need to succumb to this kind of nihilism. Truth and objective reality are still discernable and approachable. Philosophical objections to the Truly objective viewpoint are not the limiting factor.

"Everything is just a narrative" is the cry of those who don't have truth on their side. The current state of mass media is the result of their cries becoming louder. We don't have to go along with it.
