If Apple didn't want CSAM on their servers, they'd implement it server-side on a worldwide basis, and not on the client-side for US clients.

  They explicitly don't want to implement it server-side due to the privacy concerns of decrypting every image in iCloud Photos. Doing it on-device limits Apple's possession of decrypted photos to those likely to be CSAM.

    Apple can already decrypt your photos in iCloud - that’s how you can log in at iCloud.com and see them.

      Of course they can; The point is that they don't want to if they don't need to.

  Apple obviously does not want CSAM on their servers. As the document states, they do not want to scan all images server-side for privacy reasons. They just want to flag the positives while keeping privacy standards as high as posible for everyone else.

  Implementing it server-side would require the content to be on their servers to scan, doing it client-side reduces that risk (or, as they claim, don't want to do that for privacy reasons, or most likely a mix of both those two reasons).
