Do you really have freedom of speech in regard to social media?

[jehen]

You misunderstand what freedom of speech means - It only means that the government, by force, rule of law, or threat of punishment, cannot restrict your speech or impose prior restraint. But there is no such protection of your utterances in the marketplace of ideas. If no one is buying, or you get shouted down, that is not a violation of your right to free speech. Freedom of speech is not freedom from the consequences of unpopular views in marketplace of ideas - just the freedom to express them without the threat of arrest.
