It is extremely troubling to see so many attorneys and journalists responding to this week's events by making light of censorship by corporations that hold monopoly power over public discourse.
Censorship is easy when you're censoring unpopular opinions or people. This is why the Bill of Rights was designed to protect against majoritarian impulses.
Attorneys are trained and professionally entrusted to protect against majoritarian impulses to censor. Journalists are also trained and (theoretically, at least) professionally interested in remaining vigilant against censorship as well.
First Amendment jurisprudence is quite apparently overdue for development in response to technological advances, including to account for the monopolization of public discourse that technology has made possible.
Those trained to protect against majoritarian impulses to censor unpopular speech should be agitating for development of jurisprudence to account for technological advances, not parroting the banal and outdated point that "the First Amendment doesn't apply to private companies."
