Why is it weird? Social media has existed for around the same amount of time for all western countries, and people have noticed the harm at around the same time everywhere.

Why do you require some special interest? Ordinary people are seeing the harm and demanding help. Tech companies did themselves no favors by locking down phones and accounts to the point that it's impossible for parents to police and/or check their kids phones.

So now that parents have been blocked from parenting, who else is going to do it?
