>And this is further normalising the government making decisions about speech where they have every incentive and tendency to shut down people who tell inconvenient and important truths.

You really should think about how idiotic this libertarian talking point is

It would be valid if you had a populace that was educated (implying that when people heard the inconvenient truths, they would be able to parse fact from fiction and not be ideologically driven), combined with a tyrannical government that would be in power and afraid of the general populace knowing that information and starting a revolt.

This situation is pretty much impossible. How can an educated populace elect that government in the first place? If the population was dumb and elected a fascist government (i.e USA), they would just ignore anyone speaking inconvenient truths (i.e how MAGA is blind to all the stuff that is going on).

Secondly, information dissemination is pretty much impossible to stop these days with everyone being on the internet all the time.

The only people who complain about government silencing them these days are racists who wanna push some racist or "anti-woke" narrative, or the brainrotted people like anti-vaxxers. Because in their mind, they live in this false reality where they believe that everyone is brainwashed by the evil government and they are the actually "woke" ones.
