I am supportive of Apple’s new child protection policies. I spent two years helping to build some of the tools used for scanning and reporting content (EDIT: not at Apple). There are a few sentiments in this thread that I'd like to address.

> Yeah, and none of these assholes (pardon the language) is willing to spend a penny to provide for millions of children suffering of poverty: free education, food, health, parental support. Nothing, zero, zilch. And these millions are suffering right now, this second, with life-long physical and psychological traumas that will perpetuate this poverty spiral forever.

Many people in child safety and I, personally, strongly support policies that enhance the lives of children, including improved education, food, access to health services, and support for parents. To your point, though, it's also true that many political leaders who vocally address the issue of child sexual abuse on the internet also happen to be opposed to the policies I would support. Like most political alliances, it is an uncomfortable one.

> Anyone questions you, just destroy their reputation by calling them a pedophile.

I see this sentiment a lot. I have worked with people across law enforcement, survivors, survivor advocates, NGOs, social workers, private companies, etc. and I don't know anyone who responds this way to people raising privacy concerns. At worst, they might, rightly or wrongly, consider you alarmist or uninformed or privileged (in that you don't have images of your abuse being actively traded on the internet). But a pedophile? I just can't imagine anyone I've worked with in this space accusing you or even thinking of you as a potential pedophile just because you're opposed to content scanning or want E2EE enabled, etc. I suppose maybe someone far, far removed from actual front line workers would say something so ridiculous.

Separately, I want to suggest that there are paths forward here that could include risk controls to reduce the risk that this technology gets extended beyond its initial purpose. Maybe NCMEC could provide verifiable digests of the lists used on your device to verify that additional things haven't been added to it. Or there could be public, concrete, transparent criteria for how and when a lead is referred for law enforcement action. By designing this system by which the matching occurs on device against a list that can be made available to the user, Apple has made content scanning far more privacy-preserving and also created avenues by which it could be further regulated and transparent. I'm very excited about it and, honestly, I think even the staunchest privacy advocates should be cautiously optimistic because it is, in my opinion, a step in the direction of less visibility into user data.

I think that privacy advocates are arguing in good faith for protecting society from a surveillance state. I think that advocates of scanning are arguing in good faith for protecting children. I also think that both sides are using language (screeching on the NCMEC side, comparisons to hostile regimes on the other) that make it very hard to move forward. This isn't pedophile privacy advocates vs. surveillance state NCMEC. Neither of those groups even exist. It's concerned citizens wanting freedom for all people vs. concerned citizens wanting freedom for all people.
