What I think is happening is that governments all around the world are seeing Big Wars brewing on the horizon, and preparing by having extensive media control mechanisms in place for when those turn into reality.
See, one thing a country must do to have a chance of winning a war, or at least not losing it badly, is to have a population strongly aligned with the war effort. That alignment, in turn, needs the population to be fed, and to believe in, all the propaganda the government puts out about how the war is going. Conversely, the enemy country tries to undermine that with counter-propaganda to reduce the other side's morale.
Back when a small group of media companies produced information, it was easy to control the flow of information for propaganda purposes. With the Internet that doesn't work, both propaganda, counter-propaganda, and opinions that are neither and go against both, flow in all directions. That's great when things are peaceful, and everyone is just having fun, doing business with everyone else, and arguing about minor grievances, or even major ones but that don't lead to existential risks. But it's very, very bad when you need to win serious wars.
So my take is that everyone but the kitchen sink is using age verification to install the infrastructure needed for full-on control of information flow, using youth outrage to learn the bypass mechanisms the most engaged will find and use, and then closing those loopholes one by one, until only a tiny minority is able to do so. Then, if (when) the wars come, a flip of the switch will enable similar strict limits on everyone. And propaganda can then work as expected.
If that's the case, we'll see governments doubling and tripling down on it, no matter the costs to corporations. These will either adapt or adapt. Those who refuse, too bad for them, and for us who'd prefer otherwise.
