(This is the final post in a five-part series on regulating online content moderation.)
In Part III, I showed how it is possible for private actors to remove an unpopular viewpoint from the internet by preventing websites that express that viewpoint from operating, a phenomenon I call "viewpoint foreclosure." In Part IV, I explained why every lawful website should have the right to exist—that is, to stay online. In Part II, I argued that regulating core intermediaries—the entities that administer the internet's core resources and, thus, the entities capable of effecting viewpoint foreclosure—would not run afoul of any First Amendment right to editorial discretion.
In this Part, I explain how the state can prevent viewpoint foreclosure by guaranteeing certain basic internet rights. To identify these rights—the bare minimum case for the state to intervene in private content moderation—we simply need to determine what a person requires of others to stand up a public website.
