>and what was the reason for doing the scanning client-side then when they still upload it? Probably so that China cannot force Apple to hand over arbitrary images in iCloud (or all images in iCloud). With Apple's design the only images China can get from you are malicious images that people send you. If Apple scanned every image serverside without any clientside scanning, then theoretically China could get all newly-uploaded iCloud images.
