Misinformation and lies can directly cause harm - i.e. scaring/deluding people into not getting a vaccine for COVID-19. Any blatantly incorrect speech where the expression alone can kill others should be evaluated for censorship. Even the founding philosophers of free speech agreed that expression should be curtailed when it would cause harm to others.

Also weirdly enough, Galileo was censored because he insulted the pope, not because of his theories on heliocentricity. Galileo tainted (part) of his objective scientific truth by injecting his own biased personal vendetta into it.
