No government is telling Twitter what it can or can’t include or exclude from its platform. It has nothing to do with free speech, since there is no federal or state government involvement. But it is being talked about in mainstream media, and by otherwise intelligent people, as a “free speech” story. There is nothing particularly remarkable about this story other than its magnitude, since rich guys buy companies every day of the week. Through the incorporation doctrine, this applies to state legislatures as well as the U.S. The First Amendment says in part that “Congress shall make no law … abridging freedom of speech …”. Two unrelated current events illustrate the importance of knowing what’s in our Constitution.
