If you read Free Speech: A History from Socrates to Social Media you'll find this "irony" repeated throughout history. It's a problem of human nature, and that's what ideals arduously seek to overcome.

The history of speech codes doesn't provide evidence for this claim. Actual historical Nazis were arrested for violating hate speech laws in the Weimar Republic, and used those arrests to promote their cause and their own victim narrative. Then when those same Nazis came to power they used speech laws to ban political dissent. Speech codes in the south in the US were used to arrest and harass civil rights activists on the basis that the were promoting racial animus and hate. The US used to lock people up for protesting the draft along similar arguments.
Anywhere you look speech codes are either used for oppression, or are useless in stopping hateful people. This happens because the either operate like the Streisand Effect or prohibit legitimate discussion and create zone of forbidden speech where hateful people can gather and disseminate their nonsense free from scrutiny and public debate. I highly recommend Free Speech: A History from Socrates to Social Media by Jacob Mchangama[1].

It's a bit unfortunate and almost as if he has never read about the constant barrage of pro-smoking propaganda, or anti-climate change propaganda, or anti-rohingya propaganda in Myanmar ended. Propaganda succeeds because of the resources being poured into it. He also seems to not accept the slow and continued polarization these efforts of propaganda have on society which in turn hurt democracy and therefore threaten free speech even more in the long run.
Absolutist free-for-all no-holds-barred free speech could work fine where everyone can speak with their own voice without being drowned in a cacophony of a thousand bot accounts repeating arguments made in bad faith meant to poison the discourse.
