That's not what I'm saying. Apple is required by law to report images if they have "actual knowledge" of CSAM. Courts aren't too kind about superficial technicalities like "that output label wasn't trained" when Apple is doing on-device ML classification of pictures to identify content. By proactively scanning for selective hashes they can say they're doing something without being required to report a less-accurate ML output. That's also why this only applies if connected to iCloud; otherwise they don't have "knowledge" of it.
