> Apple says they chose to configure it such that the feature runs only on the files that are uploaded to iCloud using iCloud Photos This must be implemented in software. A bug in this software that causes the "only on files that are uploaded" return the wrong boolean value means it will scan local photos. I never said random files on the filesystem. That's your strawman. In any case, it could well happen as well. Something is deciding what to scan, and that's software.
