I'm sure the crypto part is well implemented. However, I make the prognostic that within the next 2 years, the Chinese government will force Apple to use its own database of "objectionable" content and will require that the on-device photo roll be scanned, not just iCloud (they already have access to that). And probably not just China, because any LEA and secret services would love to have the ability to use such a system for ad-hoc searches: dear Apple, for those users, please extend the database source to this new one we maintain and enable scanning of all on-device pictures.

> I'm sure the crypto part is well implemented. If it is, that's bad for human rights. The crypto part protects Apple and their under-specified list sources from accountability. Without the crypto the system would just send you the database of bad hashes and snitch on you based on it. Your privacy would be no worse, but at least researchers would have some chance of detecting when the system was being used off-label to enable genocide.
