Aren't you ignoring the fact that actual authoritarians are using the lack of moderation in FB to spread misinformation and incite populism and take control? This has occurred in India, Sri Lanka, Myanmar, and I would argue currently occurring in the US.
I also used to be a free speech absolutist, but I'm not anymore since I realized that it doesn't actually result in the kind of educated discourse and debate where truth prevails (as libertarians seem to think it does) - it results in 8chan and QAnon. Human beings aren't rational, and are rife with cognitive biases towards bigotry and cruelty that can easily be hijacked by populists.
