The crux of their argument is twitter is a public square, which it is not. Twitter is a private platform selective in what users it allows to participate, which is their right as a private company. Twitter (et al) want it both ways. They want the no-liability of a common carrier, in the same way that the phone company or the postal service aren't liable if people use them to plan or carry out illegal acts. But they also want the "private company" right to say who and who cannot say what. The weird decision to withdraw verified identities for certain users for example, when clearly, they are still who they say they are and who Twitter previously confirmed them to be. The selective enforcement of the ToS. Well, they're going to have to choose because the current situation isn't sustainable. Neither will be good for their shareholders.
