The marketplace is not broken merely because one party's goods aren't selling. If I make scratchy toilet paper and people don't buy it, it's my fault, not the market's. The fact is that the media elite have little credibility these days among the general public, their wares suck, and people are investigating alternatives. The solution isn't censorship. It's becoming more credible.
Why should credibility matter? That is to say, how can the average person know that what they're reading is credible or not to make that determination and say "oh, CNN reported this and it's credible! Must mean that CNN is becoming more credible and I should watch it more because they have a better product" rather than "CNN is reporting this but it doesn't line up with what I want to believe, they must be wrong and not credible". Your metaphor doesn't make sense in a world where news stories are looked at skin deep, where someone doesn't even know that the toilet paper is scratchy it just _looks_ scratchy from the label or uncle Joe told me that it must be scratchy because it's made by Proctor & Gamble.
Credibility matters, because people really do want to base their opinions on facts. CNN existed for two decades before Fox News got popular. That wasn't the case because everyone agreed all the time back then. It was because the media respected its role in society and at least tried to be objective.

Not really, confirmation bias is a real thing for all human beings. The issue here is that there's a fundamental disagreement about what constitutes a fact. Objectivity in reporting is also subjective, funnily enough. If I consider NPR to be very objective because the dead-pan monotonic voice of the announcer simply says a direct quote from a member of congress, I can talk to a relative who will tell me that same NPR story is biased because they reported on something they don't agree with.

There are _plenty_ of news outlets that still respect their role in society. The difference is that 20-30 years ago, there wasn't a deluge of information or misinformation readily available to get those dopamine hits from confirming biases.
