Call me crazy, but I don’t think corporations should be in the business of scanning everyone’s private data on behalf of “the authorities”.
Too many ways it can go very wrong.
Also, I feel like there’s probably not much of that on apples servers… Like wouldn’t that mind if cloud network be the last place you’d want to put illegal pictures? If I was trying to hide some felony pics or data I wouldn’t be trusting a large corporations cloud services.
