| 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. |
I believe the hardcore freedom of speech view has a few important underlying assumptions:
1) More information is better, and shining a light on something is better than trying to selectively hide it, because eventually the real truth comes out through persistent discourse. This is only really possible with the maximum amount of information, and especially all viewpoints laid out on the table with the least amount of obstruction.
2) People are broadly able to parse out untruths, or irrelevant positioning, or anything that is of low quality, and they will not be persuaded by it. This isn't true of everyone, but it is true of enough people; that's an inherent assumption of democracy. We live (or want to live) in a free market of ideas, where ideas can compete, and the market (what people are persuaded by) will be broadly rational and land on the best position in aggregate, even if some people are persuaded by bad or malicious arguments.
3) Limiting the visibility of any information detracts from the overall quality of discourse because it robs people of the ability to improve their thinking. It negates the possibility of refutation, because the untruth is hidden. Giving people all information, including misleading information, in the long-run leads to a population that can have better discourse and evaluation of all the information thrown their way.

I think the above puts the ideas in the best possible light. However, I disagree with enough of these assumptions that I can't take this worldview myself. My main counter to these ideas is that, similar to (pure) free market proponents, it takes on a very idealistic view of rationality that doesn't match real behavior. In practice, people have to take shortcuts to understand things—it's inherent in human conciseness—and those shortcuts can be exploited. I don't believe this is something we can grow past on a large societal scale, because it's embedded in how we think. To improve the quality of discourse, we have to explicitly protect against these biases. There are a whole host of difficulties there, too, but I think they are more surmountable than all the downsides of allowing deliberate manipulation and misinformation to spread broadly.
