PRISM is a government surveillance program that gives the National Security Agency (NSA) access to data from users of major internet services like Google, Facebook, and Microsoft. It’s stated that the NSA has direct access to these tech companies’ US servers, but both the tech companies and government officials claim that the data is only collected with court approval.
In an interview with WIRED magazine, Edward Snowden, the contractor that leaked these documents expressed his concern over this surveillence:
Another troubling discovery was a document from NSA director Keith Alexander that showed the NSA was spying on the pornography-viewing habits of political radicals. The memo suggested that the agency could use these “personal vulnerabilities” to destroy the reputations of government critics who were not in fact accused of plotting terrorism. The document then went on to list six people as future potential targets.
