Using macOS 26 and iOS 26 I was unable to reproduce their findings. I airdropped a photo from my iOS device to my laptop, and nothing in `mdls`, `xattr -l`, `exiftool -s`, `rg -i` showed my name.

It wouldn't surprise if Apple had fixed this, it's the sortof thing they would fix, but it may be worth trying with 2 devices not from the same iCloud account. Wouldn't surprise me if the code paths were subtly different in that case.
