Agree or disagree? all feb 10 soobin

Agree Agree to some extent. Internet freedom can be sacrificed only to a certain extent to fight piracy. Getting rid of internet freedom is basically the same thing as shutting out the communication lines of the world. The source of the reason why piracy is done is mainly due to the fact that people can't afford the items that they wish to use, or need to use, because they are ridiculously overpriced. These industries don't think that way because they want profit, however, if piracy was stopped, then no one will buy their products anyways because they still can't afford it. Popularity of the product will decrease, and the marketing of the product basically just failed. We need to compromise something so that piracy is decreased until there is no more. But suddenly stopping everything in one shot with something like SOPA isn't the way to go. Disagree I disagree. The internet should be free and open. We need to educate people not to download pirated software, movies and music. Doing so is the same as stealing from a shop, which most people would not do. Most people would be prepared to pay small amount for the right to download these things. If governments try to remove websites, it is the same as censorship which sometimes happens in dictatorships but should not happen in free societies. We really need freedom for the internet, so that we can easily share our own ideas, and thoughts. Unlike China, where people can't even talk gossip about governments, which is a basic human right. But China is still very famous for internet piracy. The United States should not have the power to prevent freedom of internet because they are not the world's police force. They should not have the power to dictate what happens in the rest of the world. That's why internet freedom should not be sacrificed.
