And, of course, I would be remiss if I didn't mention that the reason the NSA was so easily able to assemble such a massive apparatus to spy on the world was because the data was sitting right there waiting for them to scoop it up. As Edward Snowden and others have explained, the government essentially deputized many social media and messaging companies to do their snooping for them by compelling them to share these massive targeted datasets with them. In some cases, they just outright hacked the data using intercept techniques authorized under the Patriot Act.
Owing to the fact that this forum has a variety of international users, you can be sure some of the messaging traffic is getting scooped up even as we type, though its thankfully anonymized and would require a formal request from the government to the site owners to get identificatory information on a user or group of users (which they would be legally disallowed from telling us about).
Facebook, Apple, Twitter and other platforms (perhaps after performing a sentiment analysis) made a great show of claiming to keep our data safe and striking a tone of non-compliance, but only after legislative change was imminent. They had been quietly providing the data for years in most cases, but absolutely didn't want people stopping to say "hey, why do they have all this stuff anyway?" Blaming government overreach and striking a public adversarial posture was a slick PR move, and one easily engineered fresh off the victory over net neutrality that painted Big Tech as somehow on the side of the little guy. It would still take most of them a couple years to standardize end to end encryption in the messaging components of their services.
But the story of the government surveillance programs wasn't just how uncomfortable it made people that the state was using this information. That private sector actors were storing and freely sharing amongst themselves so much of our personal data is just as disquieting.
