::::The policy is at WP:NFCCE: "Note that it is the duty of users seeking to include or retain content to provide a valid rationale; those seeking to remove or delete it for non-compliance with criterion 10c are not required to show that one cannot be created—see burden of proof." The image File:DuluxTin.jpg currently violates WP:NFCC#10c, although I agree that it would be very easy to correct this by simply adding a fair use rationale.
