TV news/documentary broadcasts have a "fairness doctrine" in most of the democratic world [1], meaning both sides of political discussions must be presented. This is a very good bit of legislation which makes television (and radio) broadcasts much more impartial and open minded than a typical social media bubble.
TV programming might well be "mind rot" to some. But to equate TV news/documentaries with social media is a poor comparison. One is demonstrably worse.
