Wasn't the only "censorship" twitter has done simply against harmful misinformation and hate speech? What exactly is twitter censoring that's outside of those two?
I haven't used HN long enough to know why I can reply to some posts but not others, so sorry for this top level
The Hunter Biden laptop story.
This story was broken by the right-leaning New York Post. Twitter banned its sharing in the weeks before the election, claiming it to be misinformation (with the implication that the leaking of its contents was part of a Russian plot).
~2 years later (when its relevance is greatly diminished) both the Washington Post [1] and the New York Times [2] have confirmed the major aspects of this story.
This was a coordinated censorship campaign, and a free speech platform would have allowed it to get the the sunlight it deserved.
Now, does it appear the NY Post's coverage was slanted and, in some areas, inaccurate? Yes. But that is where the rest of the media (including and especially Twitter) should have stepped in to perform its function in an open society: producing more and better speech.
Now, there are about a million other things that are probably obtained illegally talked about on twitter, but even so, obtaining and posting someone's tax returns online is actually illegal, and it was also for a presidential candidate, so it really should have qualified under the same rules to be censored if Twitter was consistent. Yet that was never blocked on Twitter.
that's the problem. These days anything you don't agree with can be considered harmful misinformation and hate speech. A year ago, doubting the almost 100% efficiency of masks or vaccines was "harmful, dangerous and may result in deaths", these days it's "common sense and valid skepticism".
