Anyone in the United States has the right to copyright their work to make a profit from it. That includes proceeds from online sales. Online piracy should be reduced to prevent copyrighted material from being used without authorization from the owner of the work. No one gives away hamburgers for free at fast food restaurants, so why should intellectual property over the Internet be the same way? For those who don't pay "fair use" fees, it's time to clamp down on online piracy and give companies the authority to shut down pirated material.
Congress can try to govern the internet, and they can block certain things in this country alone, but they can't keep things off of the internet, and they can't keep people from doing what they will with the data that's on it. The internet is the wild west of this era. And it can't be contained. Someone once said that the best way to beat piracy, is to deliver a better version of the things being pirated. And this speaks true for the internet. If there was a way to monetize media streaming, then piracy would be nonexistant, or at least cut way down. Hulu and Netflix help, but they still aren't exactly right. The cost of media is too high.
To do so would allow big companies even greater power over content than they already have presently, and they have a lot as it is. If anything the rules on piracy should be lessened, not made stricter. There are many ways that content is used that should be legal but as it is is illegal. So no I don't think Congress should pass anti-piracy laws, in fact they should lessen the laws already existing.
No, piracy is already illegal. New legislation is not needed. It seems to me that it would be another way for the companies that already have legislators in their pockets to write laws that further their own agendas. It wouldn't just be laws to protect people's intellectual property, but ways to shut down any website that has a link to copyrighted material. Many websites, blogs, etc. are open to posting by the public. Anytime someone posted a link to a copyrighted movie or music file on your blog, it would be subject to blacklisting. This is too much power.
Most members of Congress barely understand how the internet even really works, and what understanding they do have probably comes from the lobbyists who work for big intellectual property holders. While online piracy is definitely a legitimate problem, a ham-fisted response written by lobbyists-- which is what Congress would more than likely produce-- will crush consumer rights while doing little to actually prevent piracy.
