Well its simple. There is overwhelming evidence they didnt play fair. They are not supposed to editorialize tweets (violation of sec 230 protection). They were free to let Nytimes publish supposed hacked tax returns yet blocked/ censored Nypost and other twitter users from sharing URLs in the same context. They got caught. Now its up to the congress on how they want to proceed to strip them of sec 230 protection and let the trial lawyers sue them into oblivion.
