why not use rclone

Because icloudpd supports downloading photos from icloud and rclone does not (yet): https://github.com/rclone/rclone/pull/8734

"why not use rclone (?)"

This is the correct - and obvious - response to something like this.

Unfortunately, I believe that rclone has no support for iCloud photos at this time.
