I honestly do agree artist should have control over there work but not when it interferes with public interests. If you look back at What copyright law was when this country first started and what it is today it'll be totally different. For most of the history of copyright law going back to the statute of ann Copyright law had built in restrictions.
After 25 of years creative property would enter into the public domain. Now I'd honestly doubt anything would ever enter the public domain.
Originally copyright only gave you the creative right to create and distribute only the original work and Only a very small percentage of works even had copyright. IE If you wrote a book you didn't have the right over the movie or play unless you filled a copyright for those to. Now Copyright covers not only the original but any derivitive works any parodies anything you that can be traced to something you create can now be brought up in court. Which leads to Situations like this

Now Before We on any farther One important thing to talk about is the DMCA. The patriot act of copyright law. Now I could give alot of examples for this. I've been on the internet alot and frequent sites like digg and reddit. And have heard some fucked up uses from for the DMCA. But I'll use the 2 examples in the book. Also consider the mafia tactics used by the RIAA and MPAA. they're are many of these.

Im gonna finish this with a few quotes.
"Never in our history have fewer had a legal right to control more of the development
of our culture than now."
"Never has copyright protected such a wide
range of rights, against as broad a range of actors, for a term that was
remotely as long."
"The opportunity to create and
transform becomes weakened in a world in which creation requires
permission and creativity must check with a lawyer."
This is honestly My opinion but copyright should not grant someone complete control pf there work for the sake of public interest. Copyright law needs to change to evolve with the emmergence of new technology to meet the demands of comsumers. It's happened with photography film TV Radio The VCR and I needs to happen with the internet. I think Copyright law needs to regress to what it once was instead of what it is now.
