Labeling as an answer to DRM?

Indicare has an interesting article> written by Natali Helberger about the advantages and limitations of
labeling requirements as an answer to DRM. Such labeling requirements can be found, e.g., in the revised German Copyright Act, and are also being discussed in the U.S. Congress. In certain aspects, they remind of Judge Easterbrook's well-known phrase in ProCD v. Zeidenberg and the discussions surrounding ProCD: "Competition among vendors, not judicial revision of a package's contents, is how consumers are protected in a market economy."
