Freedom speech.
This is a "global" (western) movement, and under the excuse of "protect the children" they are pushing certain conditions that force every system to real personal identification.
Why do that when in practice they already have being collecting ALL the information? (just see Google how integrates everything and any visit in other place automatically changes the view in other products, and most accounts are identified).
BECAUSE, not bound access can claim that was made by another person.
This is just an step to ENFORCE identification. And once identification is implemented, then punish certain future behaviors. Under excuses of spreading misinformation, "hate speech" and whatever, they have the intention of implement hard censorship.
Add to that a flood of false anonymous people that are just AI bots, and they will control most of it would happen in Internet.
If they care about children they won't enforce age verification. They will instead give tools to parents to configure safe setups for children. It's just as simple as account/browsers configurations and webpages that label their info based on the level required to access.
All of this is half implemented already for those who doesn't now. Legal p*rn sites usually have HTML meta labels indicating that it's adult content. These systems could be enforced and extended. They are easy and doesn't compromise any data.
But they push for real identification against central systems. Do you really believe that this is about children?
It's a ridiculous excuse. Specially while at the same time they hide Epstein case and lots of real children abuse.
