Many people come to a conclusion that that the classical definition of free speech is easily abusable when enough people gather and utilize free speech to promote hatred, closed-mindedness and bigotry. Thanks to free speech instances we get hoaxes like the ones that way 5G is a mortal danger, vaccines are a mortal danger, women, Muslims, Jews and people of color are despicable, and many other interesting "100% verified truths and facts".
I know that the perfect solution for this problem does not conflict with free speech, but if that perfect solution (whatever it is) doesn't come soon enough, the world will get fed up with waiting and implement imperfect solutions, and limiting free speech is first on that list.

the classical definition of unfree speech is easily abusable, which is why free speech exists.
If an idea is bad, the best way to beat it is with better ideas.
Of course some bad ideas are good at spreading, or otherwise persuasive. But if you take the big picture view, the vast majority of really bad ideas and statements have been imposed centrally and have persisted by latching onto the levers of censorship and censoring all competing viewpoints.
The level of censorship and central control of information is already far too high in our world.
