If I tell you to take down your comments, I am not censoring you. I’m speaking. It’s only censorship if I can force you to take them down.
The same is true for federal officials; just telling someone to shut up is not censorship. Without an actual threat of force, it’s not censorship or intimidation.
Note that I’m not arguing that intimidation cannot and does not happen. But intimidation requires an actual threat. Not just an angry email.
The ironic thing is that federal officials can speak freely because of the First Amendment. It gives them license to speak because actual legal protections exist for citizen speech. The power of federal officials is well constrained under U.S. law. They can tell a media company to change their content, and the company can say “no.” Because of the First Amendment.
