Booting people off of platforms merely reinforces their pre-existing beliefs, and further radicalizes them.
COVID-19 has added the additional element of this new concept of "disinformation". The argument is seductively simple: "being exposed to this information could lead you to engage in patterns of behavior that harm society. Therefore we can conceptualize this speech as being an indirect form of violence/negligence and therefore we have a moral obligation to remove such content".
Many may disagree, but I think we need to throw out this concept of "disinformation" entirely. I don't believe in fighting "bad ideas" by suppressing them, I believe in shining a light on them. Let the truth fight for itself. (And of course now comes the classic counter-argument: that the evils of disinformation possess a virality that makes them spread far more easily than the truth, being that truth is nuanced and difficult to acquire whereas bad information is seductively simple. I won't address that argument here but personally I think it's a very dangerous way of thinking)
