The Constitution grants to Congress the power "To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries." U.S. Const., Art. I, ยง 8, cl. 8. We have often recognized the monopoly privileges that Congress has authorized, while "intended to motivate the creative activity of authors and inventors by the provision of a special reward," are limited in nature and must ultimately serve the public good.
(Emphasis mine)

My reading is that: In other words, where the prime intent of a copyright statute (change) is to give corporations more control and profit at the cost of the public good, it might be appropriate to toss the statue, or at least limit it applicability to the point where it, once again, really does promote the public good.
