Major technology and Web companies — not limited to Google, Facebook, Twitter and Microsoft — will not be allowed to promise to protect users' privacy should CISPA pass Congress. For those out of the loop, CISPA will allow private sector firms to search personal and sensitive user data of ordinary U.S. residents to identify this so-called "threat information", and to then share that information with each other and the US government — without the need for a court-ordered warrant. . . . those who signed up to services under the explicit terms that data would not be shared — with perhaps the exception of the U.S. government if a valid court order or subpoena is served — would no longer have such rights going forward.
