When I was growing up, access to the marketplace of ideas was controlled by the owners and editors at the three TV networks and a few periodicals. You could say that it was censorship of a kind, but it wasn’t run by the government, and it wasn’t partisan. It kept out extreme ideas. It was a censorship of moderation and good taste.
First cable TV, then the internet, and finally social media have blown up this model. Today, the extremes rule, to the benefit of the owners of the social media companies. Any moron with a modem is entitled to broadcast his opinions for the entire world to hear. As a result, bad ideas drive out the good ones, partisans live in bubbles, and both sides fear the fringes of the other.
This situation is unsustainable. It cannot last. We are headed for a new model of censorship, which is already evolving in several countries throughout the world. This one will be run by the government, and will be partisan. The only question is who will control the new regime. The most likely answer is the right in the short run, and the left in the long run.
