The song's criticism on mass media is mainly related to sensationalism.

"Good" things are usually not sensational. They do not demand attention, hence why the code of known/unknown based on selectors for attention filters it out.

Reference Hans-Georg Moeller's explanations of Luhmann's mass media theory based on functionally differentiated systems theory.

Can also compare to Simone Weil's thoughts on collectives and opinion; organizations (thus most part of mass media) should not be allowed to form opinions as this is an act of the intellect, only residing in the individual. Opinion of any form meant to spread lies or parts of the truth rather than the whole truth should be disallowed according to her because truth is a foundational, even the most sacred, need for the soul.

People must be protected against misinformation.

A critique on the Mass Media... The problem is that they want the Mass Media system to operate on the code of "True/False" rather than "Known/Unknown"... But if it were to be so, it would not be Mass Media anymore, but rather the Science System.

For Mass Media to be Mass Media it needs to be concerned with selection and filtering, to condense and make known, not to present "all the facts". Sure, they need to be concerned with truth to a certain degree, but it's not the primary priority.

This is a reflection based on my knowledge of Luhmann's theory of society as functionally differentiated systems; as explained by Hans-Georg Moeller (Carefree Wandering) on YouTube.
