The elephant in the room, is 'foreign actor'.
All of our platforms are inundated by an overwhelming amount of well crafted, targeted (specific per person) campaigns of disinformation by foreign actors.
China, Russia, Iran, and others cannot even remotely hope to stand against the West. Yet if you cannot stand against your adversary, you must weaken them.
You promote infighting. You take minor issues which can be cooperatively resolved with compromise, and seek to turn them into issues of great division. You spread falsehoods, creating useful idiots in great numbers.
You find the most radicalized, most loony of citizens that you can, and then secretly fund them.
Understand, any concept of "we do that to ourselves" is like a gnat in comparison. This is a real threat, it's been getting worse, and the common person is not capable of even understanding the concept. The common person, even when told repeatedly, thinks there is no downside to having their Pii stolen, or hacked. They simply read click bait titles, youtube or tiktok videos and 100% believe every word without any skepticism.
You may disagree with any or all of the above.
However! The above is what is actually behind the move for KYC to this extent. It's not about age verification, it's about identity. And it's not even about one westerner talking to another, it's about a foreign adversary seeking to pretend to be a domestic.
Of course, this is all rife for abuse. Of course, there are immense downsides. Yet the downsides of leaving an endless stream of propaganda, disinformation spewed at everyone including our youth, unchecked, is far far greater.
And I say this as someone that has fought for an open internet. It's already dead. It's dead because foreign interests use it as a tool to destroy our societies. It's dead because soon AI will replace most generated information.
Age verification laws are really identity laws, and any work to provide anonymous verification will fail, sadly, unfortunately, because the perceived threat is so large.
(I do not even necessarily agree with this, but if we don't understand the logic and the why of this, of why it is happening, then we're complaining about the wrong thing...)
