First amendment protections derive primarily from the fact that the Government has a monopoly on force. It's monopoly power that is the ultimate motivator for the protections. In this particular case, when every private entity with oligopoly power (de facto, not de jure, per the capital and other ICANN approval hurdles) denies your platform, then you're in effectively the same position as if the Government was denying you speech. It's why we have antitrust and labor relations laws - we recognize that monopolies or effective monopolies approach the power of Governments in ability to deny rights.
