Well that's an interesting take.
Without free speech you get shining examples like China, Russia, Iran, North Korea?
My post did not mention anything about absolute free speech, and very few are advocating inclusion of revenge porn, child porn, incitement to violence type of speech.
One would think that a powerful entity, government or corporate, (particularly those portending to be a public square type of platform) should be able to censor, suppress, shadow ban or de-platform without transparency. In particular, I'm speaking of political, policy and scientific thoughts and opinions. It is this type of speech that should not be privatized (Elon included).
Censorship in these areas are a threat to democracy. The government, in collusion with media censorship is how democracy is lost.
