Republicans are generally against government meddling in business. Yet many Republicans are threatening to break up Facebook after the decision to ban Trump as seen here, here, here, or here.

If the government shouldn't meddle in business then shouldn't Facebook be allowed to do as they please? I understand if they criticize Facebook or use some other platforms. But why would they want to use government power to attack a private company? How can “not meddling in private business” and “breaking up a private business” go together?
