I disagree wholeheartedly. Censorship doesn't become not censorship just because you agree with the arbiter. Who determines what is true or false if there is no discourse?
Obvious lies about the vaccine were apread regularly. Many of Trump's statements were easily proven false, which is what got him banned. Again, people weren't being banned over opinions, unless they were violent or discrimatory (which leads to harm to individuals). Lies and proven false statements are not free speech.
