Government Control
Communication is necessary to organize political takeovers. Governments must control external and internal communication capabilities to reduce threats of social rebellion. The Internet is an ideal media outlet for providing foreign information and viewpoints that could spark a rebellion. Some governments censor the Internet, including email, blogs and websites, for content on topics such as anti-government sentiment, human rights and radical social opinions.
Personal Freedom
Civilians with access to outside viewpoints can compare and evaluate standards of living. Personal freedom includes the right to access information and to form opinions and make personal decisions based on as much information as possible. Censorship is disadvantageous for civilians seeking knowledge to explore a broad range of ideas, concepts and ways of life that might contradict their government's interests.
Fraud Protection
The Internet provides consumers with a wide range of products and services. Unfortunately, the online market place is an ideal environment for illegal activity. The United States Chamber of Commerce supports Senate Bill S3804: Combating Online Infringement and Counterfeits Act. The bill would give the U.S. government the power to shut down sites that knowingly violate copyright laws.
The Chamber believes businesses and consumers are at risk from widespread counterfeit and fraudulent activity. Free speech advocates object to the bill's vague wording and say that sites such as Youtube and and blogs that utilize online media articles could become targets under this legislation. The bill could be a gateway to allow government greater control over the internet.
