With their plans to encrypt icloud contents by the the end of the year they would not be able to scan anyways if i user has that enabled anyways right?

The proposed scanning was on-device. They could have done it regardless of iCloud encryption.

But it only did so if the user had iCloud photos enabled.

It wasn’t scanning. They took a fingerprint of every photo and encrypted it so only if that fingerprint matched on the server side and only if 5 of those matches occurred, they could view a photo thumbnail.
