Bad: Every place that tries true free speech eventually finds the limits of what people will tolerate. 4chan is a great example. Additionally, open algorithms, as Musk intends, will allow those who craft spam bots to consistently evade the system. Users will lose faith in the system not for the lack of quality content, but for the ratio of quality to garbage. How much time sifting through garbage will people stand before finding good? Again, see 4chan.

Good: "Without freedom of thought, there can be no such thing as wisdom; and no such thing as public liberty without freedom of speech; which is the right of every man as far as by it he does not hurt or control the right of another; and this is the only check it ought to suffer and the only bounds it ought to know.... Whoever would overthrow the liberty of a nation must begin by subduing the freedom of speech, a thing terrible to traitors. Benjamin Franklin" Twitter enjoys the protections of being a public forum and should be treated as such. Additionally, Twitter went too far in censoring political opponents, which sends the subtle message that the censored argument was so good, no counterargument could be made. Without naming names (which I'm sure will trigger some bot), I've reviewed many of the censored and find their arguments were neither so good as to have no counterargument, nor so bad that censorship would be necessary. Circling back to Ben Franklin: "Whoever would overthrow the liberty of a nation must begin by subduing the freedom of speech".
