“Multiple names policy.” Stealthing potentially wildly unpopular secret programs in one country’s government intelligence agencies by using e.g. multiple different program names over time for the same program or multiple different names for similar programs in different intelligence agencies. Multiply this by the number of countries indulging in warrantless wiretapping and suspicionless surveillance. The lack of a single -gate umbrella term might deflect target acquisition by the public’s ire.
Germans were confused by a 17 Jul 2013 Bild.de article followed by a government press conference confirming the German government had averred that the U.S.A. had two Prism programs, this time with the same name, but though they accomplished similar goals they were not the same program. Supposedly the German military and Bundesnachrichtendienst learned about Prism, but not the other Prism, via N.A.T.O. in 2011.
