Free speech is really complex: for example a person may have a huge platform and shout out malicious lies that have real world consequences. The discussion and analysis of these lies will not nearly reach the original audience and the lies live on and destabilize society. On the other hand the audience does not have enough of a foundation in critical thinking to evaluate claims for themselves. So it looks like there is some need for controlled moderation of platforms but, much more room to improve critical thinking faculties in general, because this reduces that need for platform moderation.
