Probably the biggest source of ridicule and mockery against the solvency, realism, and desirability of libertarianism I'm seeing right now is coming from right-wing populists, the alt-right, and paleocons furious about right-wing views and figures getting deplatformed on social media. They assert that hoping for free market fixes is delusional and shunning government regulation to force equal access on private companies is cucking to the left. The main thrust takes the form of one of the favored pillories against libertarian philosophy that "it looks great on paper but doesn't work in the real world."
But just what is the valid market-oriented solution to the informal collusion of left-wing power brokers seizing the means of communication to un-thing more and more of the right side of the political spectrum?

There does not appear to be any viable means of stopping this besides regulatory action. Whether it be breaking up tech company monopolies, revoking their Safe Harbor protections, or rescinding common carrier/neutral platform assumptions for these companies.
