Despite their claims otherwise, Yahoo and Google allegedly knew the National Security Agency was collecting data.
A lawyer for the NSA says the U.S. tech giants provided "full assistance" in legally mandated data collection.
From The Guardian:
When the Guardian and the Washington Post broke the Prism story in June, thanks to documents leaked by whistleblower Edward Snowden, nearly all the companies listed as participating in the program – Yahoo, Apple, Google, Microsoft, Facebook and AOL – claimed they did not know about a surveillance practice described as giving NSA vast access to their customers’ data. Some, like Apple, said they had “never heard” the term Prism.
