There exists doctrine in constitutional law where its guarantees are deemed to apply even when the actor infringing the right is a private party. This can occur in cases where a private party is deemed to be a "state actor". See https://en.wikipedia.org/wiki/State_actor https://en.wikipedia.org/wiki/State_actor I would suggest that even large social media organizations are not "state actors", so federal constitutional protections don't apply. Of course, states are free to enact laws on their own to guarantee free speech in social media, if they want. It's just not protected by U.S. Constitution, not a constitutional right. [As an editorial aside, I'm dismayed at the general low level of understanding of constitutional rights in the U.S., even among "well-educated" people.]
