I have no doubt they will. Pandora’s box has been opened, and okay, today the scanning is only for images uploaded to iCloud, and only for CSAM. But that is not auditable and subject to change at any time without notice.
And today it is only looking at known hashes but the devices already have a capability to analyse images and even run OCR on them, this is not a matter of of these things will be weaponised but when.
Can’t believe this is the same Apple that publicly defended the right to privacy for known terrorists by using the slippery slope argument themselves. The mind boggles.
