They Keep Using That Word, "Monopoly." I Do Not Think It Means What They Think It Means.

The social media platforms aren't monopolies. If you don't like Facebook or Twitter, you can go to Minds, MeWe, Diaspora, Mastodon, Gab, Discord, et al.

The state, however, IS a monopoly.

Arguments in favor of state regulation of social media platforms aren't arguments against monopolies. They're arguments in favor of extending a monopoly's reach into new markets.
