There are lots of alternatives to freedom of speech, e.g., a totalitarian state, military dictatorship, oppressive facism...
@Pat
of course the discussion is about what the limits of freedom are
Unlimited freedom of some, will limit the freedom of others.
Most Mastodon instances are not unlimited. Most don't allow hate speech, harassment, racism, or homophobia.
And can't imagine any platform allowing, e.g., malicious code injection or DDOS attacks.
Though, I understand your point about the difference between privately owned platforms vs. forms of sovereign government.
