Glenn Greenwald said this quote

“ Every time I do an interview people ask similar questions, such as What is the most significant story that you have revealed? […] There really is only one overarching point that all of these stories have revealed, and that is–and I say this without the slightest bit of hyperbole or melodrama; it's not metaphorical and it's not figurative; it is literally true–that the goal of the NSA and it's five eyes partners in the English speaking world–Canada, New Zealand, Australia and especially the UK–is to eliminate privacy globally, to ensure that there could be no human communications that occur electronically, that evades their surveillance net; they want to make sure that all forms of human communications by telephone or by Internet, and all online activities are collected, monitored, stored and analyzed by that agency and by their allies.That means, to describe that is to describe a ubiquitous surveillance state; you don't need hyperbole to make that claim, and you do not need to believe me when I say that that's their goal. Document after document within the archive that Edward Snowden provided us declare that to be their goal. They are obsessed with searching out any small little premise of the planet where some form of communications might take place without they being able to invade it. ”
