CISPA has been criticised by advocates of Internet privacy and civil liberties, such as the Electronic Frontier Foundation, the American Civil Liberties Union, Free Press, Fight for the Future, and Avaaz.org, as well as various conservative and libertarian groups including the Competitive Enterprise Institute, TechFreedom, FreedomWorks, Americans for Limited Government, Liberty Coalition, and the American Conservative Union.
Those groups argue CISPA contains too few limits on how and when the government may monitor a private individual’s Internet browsing information. Additionally, they fear that such new powers could be used to spy on the general public rather than to pursue malicious hackers
So who wants CISPA?
CISPA had garnered favor from corporations and lobbying groups such as Microsoft, Facebook, AT&T, IBM, Apple Inc. and the United States Chamber of Commerce, which look on it as a simple and effective means of sharing important cyber threat information with the government.
