I’m curious why Meta would benefit. Meta seems wholly unnecessary, the verification can be done at the OS level, completely in the hands of Apple/Alphabet and maybe Microsoft.
If anything, Meta’s utility would seem to shrink if the OS handles proof of being a real person.
Regulatory capture through a higher barrier to entry. Any social media platform that wants to compete with Meta's portfolio will now also need to have an age-verification system in place (which is guaranteed to introduce higher costs). Meta can likely afford to eat the costs here as a tradeoff for the higher impact on smaller players.
It also gives them more information on users as a bonus. Further, verification with a real ID is also a quite effective barrier against excessive bots.
Look beyond the CA law, states have already passed laws that put the liability on app and website developers to ensure users aren't kids, there's no passing the buck to Apple or Google.
Meta's entire business model lives on ad deals that are not on the frontend. They are in the data business and this campaign is to get access to more data without an option to opt out. Who takes the data doesn't really matter.
1. It deflects any obligation that would have landed on Meta itself to do age verification (which is what the regulators have long asked for).
2. It gives Instagram/Facebook/Messenger the ability to deliver the right ads to the right audience. It's free targeting data.
If anything, Meta’s utility would seem to shrink if the OS handles proof of being a real person.
