@16bwhitt COVID vaccination has prevented COVID infection for many, so that statement isn't even false. One could say the vaccines in question do prevent infection and still be correct, despite the fact that statistically speaking it really doesn't. No vaccine has been 100% in this case, few of them are better than 80% in this space. The "facts" in this case specifically depend on perspective and which stat you're using.
Twitter isn't a town square, nor will it ever be even if privately owned. Twitter is private property. If you want Twitter to be a town square, you don't get there by a rich guy buying it, you get there by defining it as a utility and developing a government construct that defines shared ownership.
If Musk bought Twitter, and defined things as he has said, what he does is get sued into oblivion because he's allowed everyone in his private property and done nothing to stop defamation and many other types of speech that are actually illegal despite it being his responsibility to do so. So if Musk bought Twitter and did what he suggests, he'd find himself forced to change his tune just because of established law. Because again, we haven't actually defined a public ownership of the property in question. When we do that, we also defined shared liability, which changes the dynamic.
The problems we face here is a dangerous merging of public and private property rights, against freedom of speech concerns. Which don't actually come into play until the government gets into owning the medium in question.
