> Given that it seems Meta is commissioning these laws

That's not given. Someone found some good evidence that Meta was supporting (and even supplying language) for some of the earlier laws. Those were the laws doing age checks on websites and typically requiring uploading ID documents or face scans to those websites.

I've not seen anyone provide evidence that Meta has anything to do with the laws that are like the California one, which do not require providing any documentation or proof whatsoever of age. They just required that the parent of a child who uses a device be asked to provide a birthdate or age when setting up the child's account, and that the OS providing an API that apps on that device can use to get the age bracket of the child.
