> The end of anonymity online basically means an end to the internet era itself. We will effectively be rewinding time to the 1980s, when the only news sources were controlled by oligopolies, and dissident voices were simply not given a platform.

No, in the 1980s, dissident voices had platforms. They weren't "mass media" platforms but they definitely had radio shows, periodicals and various publishing channels to disseminate their publications and broadcasts. They were incredibly important in those days, and those sources held some amount of power, in that they could expose a story, and effectively force the rest of the media to cover a subject or event they otherwise would have ignored.

This is worse in every way as it /completely/ locks them out the modern market of ideas that is the internet and ensconces prior restraint into law in a way that violates the civil liberties of every citizen, whether they are the publisher, or the consumer.

We have lost control of the internet. Those who have control intend to turn this world back into a fiefdom with their newfound power. They are otherwise working to keep the rest of the population in fear and distracted. I'm genuinely afraid our past luck will fail to hold out. They've spent 20 years to get to this point. I don't see them giving up.
