You're doing a poor job of explaining the first worldview. Which is okay, you've acknowledged that you have trouble understanding it.
This worldview has been called the "liberal consensus". What it holds is that the power to determine a discourse is inherently against freedom is corrupting, and by allowing an authority to determine that, it will inevitably be used as a weapon.
Goalposts will shift. We will, hmm, go from suspending accounts which promote the theory that COVID-19 is caused by 5G towers, to suspending the account of a virologist who issued a preprint suggesting that gain-of-function mutations in SARS2 point to a laboratory origin.
Look, both of those things might be false, but surely we can agree that if so they are false in a different way.
There were many experiments with official truth in the 20th century. The general consensus was that they were unpleasant to live under and did a poor job of actually separating truth from falsehood. Many of us don't care to repeat those experiments, the effect size was large.
If we had an oracle of truth, then censorship of falsehood would be easy and practical. We also wouldn't need democracy at all, we could just ask the oracle of truth what to do, and do it. But we don't have any such creature.
