Variations 4 and 5which are by far the most common situationsare much more troublesome. Variation 4 discloses that "Brand X" is not really 100% "Brand X" only in the copyright attribution; Variation 5 does not disclose it at all. Variation 4 is at least misleading under the FTC Act standard, and Variation 5 is an outright lie. Why? Because both of them fail to disclose in the marketing materials (the cover) or the inside packaging (the title page) that the work advertised as "Brand X" is not.
