Except, the current media outlets will use their monopoly power to suppress you, and the government will do jack diddly squat to stop them. Just look what happened with parler and Gab. Both sought to get around Facebook and Twitter and Reddit's bans on right-wing speech by building their own facebook and twitter.

In response, companies like Amazon banned them from their platform. And Gab, for example, cannot distribute their apps on either the google play or apple app store.

So no. In a normal society with a government-protected free market, you'd be right. But we currently live in what is quite obviously a corporatocracy, even if no one wants to admit it.
