The first involves software that blocks and obscene or other controversial material from children. The second gives the right to bypass malfunctioning security features on copyright material. John Vaughn, executive vice president of the Association of American Universities agreed. The association asked for an exemption for digital versions of scholarly journals, maps and certain databases, arguing they were valuable mainly for their facts, which can't be copyrighted. Presently, fair use implies that once an entity purchases a particular copyright works, they have the right to share that work with others within reasonable boundaries.
Libraries can freely lend out best sellers, for example.
Those with music and video archives do the same. Now, copyright holders can add encryption's that force the user to pay for each time they take out that CD, tape, or program file, denying that open access we all presently enjoy. This new law gives copyright holders the implied right to do this by making a crime to circumvent such a feature. It also makes it easier for companies to say you don't purchase copyright material you only rent it. Therefore, they are subject to repeated billings on that song or movie should the copyright holder desire it.
