But what’s the practical difference between scanning photos when they’re uploaded to iCloud on a server, or on device?

[tjoff]

A world of difference. Both in practical terms and principle.

To start, once you upload something to the cloud you do - or at least are expected to - realize that it is under full control of another entity.

Because of that you might not use iCloud or you might not upload everything to iCloud.

I think you might still be confused? Only photos being uploaded to iCloud are scanned. So users can still choose not to use iCloud and avoid this.

I certainly hope you didn’t get yourself all worked up without actually understanding what you’re mad at :)
