None of the systems current or proposed scan local files. They all work on cloud storage. You could not use icloud and none of this change would affect you. Also I don't believe anything in icloud is encrypted so they could have scanned it at any time.

On device hash generation is 'scanning local files.' The fact that this process is only initiated by being flagged to being uploaded to iCloud doesn't change the fact that it is being done on-device, and increases the capacity for surveillance significantly.

Yup. Good luck telling repressive regimes that the technology doesn’t exist. How is the hash list to be trusted, especially in foreign countries? Who will be reviewing the images in foreign countries?
