The problem isn't free speech in itself. The problem is the amplification of that speech by algorithms optimizing for "engagement" which practically speaking ends up being synonymous with "conflict". The medium lends itself to spreading bullshit and outrage, not quiet reflection, empathy and 'thinking for yourself'.

Sure, but is the internet to blame then? Everyone ends up in their own echo chamber, even us on HN right? And the media have been doing this for decades too...

Youtube has 55 hours uploaded every minute (iirc). Its not "the internet"'s fault that, of all the content available youtube recommended Alex Jones's videos 15 billion times.

(And specifically mothers who its algorithms think might be taken in by conspiracy thinking).
The blame lies with our peers who work at those companies. And every manager who prioritises their own advertising profits over healthy sensemaking amongst their billions of users.
