I remember the overall reaction to the Echelon revelations: "it's all tinfoil-hattery and unsubstantiated rumours". For years, just talking about it would label one as a clueless conspiracy theorist.
Now we have loads of original, undebatable documents saying it's all true. All there, black on white from the horse's mouth. This is game-changing on so many levels.
And please, let's stop with all this "it's not surprising" bull*. If it was common knowledge, how come that Edward Snowden will never be able to go home? That laws and international agreements were abused to down the Ecuadorean President's plane? That UK police abused antiterrorist legislation to get their hands over a couple of flash drives? If it was all unsurprising, how come that one Mr. Clapper was found lying not once, not twice but three times, addressing either the public or Congress? How come that the Brazilians are mad, that Germans are marching in the streets?
