Presuming you are referring to this: https://en.wikipedia.org/wiki/AACS_encryption_key_controversy https://en.wikipedia.org/wiki/AACS_encryption_key_controvers... > Outside the Internet and the mass media, the key has appeared in or on T-shirts, poetry, songs and music videos, illustrations and other graphic artworks, tattoos and body art, and comic strips. Using the encryption key to decrypt the data on a DVD is illegal “circumvention” per DMCA 1201, if it’s done without authorization from the copyright owner of the data on the DVD. If it were really illegal to simply publish the key on a website, then printing it on clothing that they sold instead would not be a viable loophole. I’m glad it is still referred to as a controversy that they were issuing cease and desist letters for publishing information when the actual crime they had in mind, which was not alleged in the letters, is using the information to decrypt a DVD.
