In Internet policy, ITIF supported both the PROTECT IP Act (PIPA) and the Stop Online Piracy Act (SOPA) in the U.S. Congress. They oppose applying Title II telephone regulations to broadband, arguing that it would stifle Internet innovation, and instead support net neutrality legislation. ITIF has praised both the U.S. and the European Union "open Internet" rulings. For similar reasons, they have supported legislation aimed at curtailing Internet piracy, stirring some controversy when they argued that data caps on Internet usage would be an effective anti-piracy tool.
