To make sure the obvious is stated: The problem here is that it means that people who make iphones and operate trojan networks on iphones can abuse children with impunity and pin the abuse on others, by manipulating the evidence apple collects.
This would be a better program if it were on an open source phone available for public audit, and stored the photos on a public secure place like a blockchain. Then, if you're an abused kid, you can take a photo of yourself and suddenly everyone knows. But with this, your parents can pay the black market to keep abusing you.
