Meta's has been listening to some concerns after all especially now after some pressure.
These changes very well could help parents moderate their teens. Meta's head of product says these changes address particular 3 concerns in an Npr interview.

I'm in the first camp. Instagram is flooded with spam accounts posting links to illicit Telegram channels where actual CSAM is being distributed.

Children having easy and often unrestricted access to social media is probably the reason why things have gotten so bad.
Every major social network should be asking for ID verification, but there should be strict safeguards on how that information is used and stored, with hefty fines for failures to safeguard.
