No. Free speech tends to mean the most powerful group determines and enforces norms through aggression, harassment, etc. Speech has consequences, and some of those consequences include harms (threats, doxing, stalking, etc.)

Mastodon is one of the freest online speech platforms I’ve been a part of, and yet also has the most rigorously enforced code of conduct. More people are free to say more things, and feel confident that doing so does not put them in danger.

Before online platforms emerged, the ability to spread a message was dependent on your ability to support it financially and logistically. Anyone can publish a newspaper on any topic, but unless you have a racist millionaire backing you up, your message won’t get very far (ahem, Deerborn Independent). Online publishing has been a haven for hate groups.
