    Entire generations of people who were never alive to remember a world where their every movement and utterance was not being tracked by the advertising/surveillance industrial complex.

    It's just considered normal now. The west is very sick.

      You spelled world wrong. China has their social credit, EU has their cameras, America has Palantir, Starlink has internet everywhere, 5G can be used as radar, global age verification is being deployed globally, ect... Babylon reborn.

        Overseas, cash is king. In Canada, and also in San Francisco, you can only tap your credit card because cash carries COVID [0].

            You weren't transacting at all in Toronto during COVID then.

            This is the endgame of surveillance capitalism: submission, or opting out. Few can, or care enough to, do the latter.

        • railgunmerlin 12 minutes ago
          curious which overseas country that doesn't fall under the 'west' has cash as king

        Of course all governments want to control every move and thought of their citizens. It makes governing easier. We expect that in autocracies.

        I don't know about The West as a bloc, but at least the USA was supposed to have respect for the basic individualistic privacy and freedom of the average citizen. We've allowed that to largely evaporate. The differences between the US and something like the PRC are rapidly eroding.

        Don't get me wrong, the US is still an order of magnitude more free but you can see a future where the trend lines are converging.

        In many ways the west is copying what the East and the Middle East are doing. It’s quite concerning that democratic governments and their electorate are going with it, but to be “fair” this seems to be a somewhat orchestrated global phenomenon. Of course it’s not good.

        That wisdom will not be much comfort to babies born last week. The first news they get in this world will be News subjected to Military Censorship. That is a given in wartime, along with massive campaigns of deliberately-planted "Dis-information." That is routine behavior in Wartime -- for all countries and all combatants -- and it makes life difficult for people who value real news.

    This is a great behind-the-scenes look at the NSA-Hepting case.

    Can't wait to read Cohn's book.

    Also RIP Mark Klein. A true American hero who never tried to turn his whistle-blowing into becoming a celebrity.

    I think Perfect Forward Secrecy has a great deal to do with how things have turned out. In the days of Room 641A, copying and diverting fiber traffic to somewhere like Utah even before it could be read, would have conferred an advantage if it was encrypted (and important enough for other attacks like black bag jobs on servers). PFS has turned ephemeral encryption into the garbage it deserves to be.

    Beware, this is a book excerpt rather than a standalone blog post, so it ends on a cliffhanger. Still a fun read.
    • SamBam 11 minutes ago
      Cliffhanger! Did it end with millions of Americans being freed forever from government surveillance?!?

      j/k It's a good excerpt, and makes me want to read the book.

      There's more info about the outcome in [1]. Long story short, the US government passed a law (whilst this case was being litigated) that let AT&T off the hook.

    Didn't see it in the actual text of the article, but as a caption of one of the images. The actual book this is excerpted from is Privacy's Defender by Cindy Cohn https://mitpress.mit.edu/9780262051248/privacys-defender/

    This is literally old news - contemporaneous with Snowden, Prism, etc. in early 2000s. Go read about the current Section 702 / FISA authorization renewal battle about which Senator Wyden recently said:

        “I strongly believe that this matter can and should be declassified and that Congress needs to debate it openly before Section 702 is reauthorized,” Wyden said in a Senate floor speech last month. “In fact, when it is eventually declassified, the American people will be stunned that it took so long and that Congress has been debating this authority with insufficient information.”

    The problem is that modern Americans politicize everything.

    There was a short period at the end of the Bush years when this was a big deal, but as soon as the gaslighting was coming from both political teams, it became a non-issue politically.

    > President Obama defended the U.S. government's surveillance programs, telling NBC's Jay Leno on Tuesday that: "There is no spying on Americans."

    "We don't have a domestic spying program," Obama said on The Tonight Show with Jay Leno. "What we do have is some mechanisms that can track a phone number or an email address that is connected to a terrorist attack. ... That information is useful."

      Everything is political. Electric cars, crude oil, rocket launches, rare earth metals, cargo transportation, public transportation, housing, taxation, data, compute... which of those aren't political?

      The problem is Americans believing obvious lies like "Privacy is a human right" and "Don't be evil" and then blaming the government instead of themselves.

      Ironically from the perspective of 2026, the actual "conservative" conservatives were the key opponents. The "total information awareness" and national ID efforts were really killed by the conservatives in congress. The "neocons" and moderate/conservative democrats were mostly fine with both.

    So, this is an uncomfortable read and comes from my personal experience. I'm posting this here as I haven't yet found great outlets and support for what I experienced, and this thread seems like a good spot. Open to outreach and support and ideas from people.

    In 2021-2022 I was vocal about the CIA being a terrorist organization (I bet many people adjacently believe similar things and are silent) and this got me attention from them. I posted several things I learned from documentaries and on the web, and from my personal background I think it was enough to trigger something in their system. From that time onwards, people I could best describe as Agents w/behavior that matches what professional interrogators would do kept showing up at public events I was a part of and in the most terrifying scenario also infiltrated my public commune.

    There's an odd history with the FBI and possibly CIA and communes such as Osho the Bagawan (see, Netflix documentary) and I witnessed firsthand how deceptive, harmful and insidious this was. In some cases I believe substances were put in my food and drink, and in the cases matching that my body would later have adverse reactions with the agent's closely observing my behavior and consistently trying to elicit Black Web conversations. I had to flee and colocate to the familiarity of family and friends since, and only recently 3-years later have I been socializing my experience and writing to my congress and house representatives. That said, that was a month ago and they have yet to provide any substantive relief or support - I asked for assistance and guidance with investigating the intelligence community for misconduct as when they're doing this to Americans without any accountability, it undermines the integrity of our Country and I believe our national security. It brings into question who they are really serving. I'm no terrorist, even if I call you one and my skin color is brown and matches what the media-funded-by-the-CIA tells you to believe. I want this story documented and heard, believe what you will, though I leave you with the story that "We know our intelligence community does unethical things, its part of what we've given them the responsibility to do so we ourselves don't have to, and now when that unethical thing has happened to you or someone you know what do you do? What do you do when everyone you turn to for help gaslights you and tells you that surely did not happen? Find proof that the organization whose job it is to go undetected, did indeed do that thing to you." I ask for some empathy and understanding, please.

      Woah. First of all I hope you are aware there are multiple mental illnesses that can manifest with feelings of paranoia etc. like text book.

      Secondly. I doubt any agency is going to hurt or drug you over that. Investigate you? Maybe. But its not worth the money.

      Just keep in mind all the dangerous people who these groups investigated that they did nothing about that went on to do bad stuff. Although I'm sure these groups do take threats seriously, I don't think you are a threat.

      I'm worried about your mental health is all. I'm not saying that in a way like "you sound suicidal" because you don't at all. You just sound paranoid. Wishing you the best brother

      • bladegash 49 minutes ago
        Yep, my thoughts as well. And I say this as someone who not only has a chronic mental health disorder that sometimes manifests as paranoia, but someone who used to work in the IC for 10 years (it has been a while since then).

        Is it possible? Sure. But it is very unlikely that much resources and effort would be devoted to someone that made a few critical comments.

        • 2ndorderthought 41 minutes ago
          Yea I mean there are hundreds of thousands of ex punk rockers with "F [insert 3 letter agency here]" on their leather jackets and whatever. I don't think these types of people are that soft skinned they'd chase down everyone who said screw them.

          I post on here all the time reminding people that tech companies are defense companies. Because I think it's important people remember what that implies.

          No one is chasing me around or anything. At least I don't think so. I'm not saying put yourself in danger for your views. But I am saying, the world isn't as scary as anyone's brain can make it be.

          These are tough times. Managing stress and mental health is hard.

          Pretty cool of you to share your experiences bladegash. I always thought they wouldn't let people with mental health conditions into those environments. Shows what I know.

            > Pretty cool of you to share your experiences bladegash. I always thought they wouldn't let people with mental health conditions into those environments. Shows what I know.

            Some mental health conditions, like mine, don’t really show up until later in life and it is at least part of the reason I no longer work in that field :).

            However, things are well managed now and I have a good career in the private sector!

      • DubiousPusher 49 minutes ago
        I would caution outright categorizing this as paranoia stemming from a mental illness. The problem with delusional paranoia and justifiable paranoia is that clinically they can present the same.

        > Just keep in mind all the dangerous people who these groups investigated that they did nothing about that went on to do bad stuff.

        There are numerous people that America's intelligence agencies have intimidated, harassed and yes drugged for similar reasons.

        OP, I hope you have been seen by a mental healthcare professional. They can help you determine the nature of these experiences. I hope you have extensively documented these experiences. Sharing that documentation with your family or others who you know to be sober in judgement is probably the only mechanism you have to distinguish if your experiences are based in reality.

        • 2ndorderthought 40 minutes ago
          That's fair. I like the way you phrased this. It's a roadmap to staying and feeling safe but also possibly getting some help if it makes sense. Everyone needs a little help once in a while, and society right now is very isolating.

      2nd post here. When I share posts matching particular phrases and labels, on HN, I've noticed them get downvoted as though by an algorithm. Would anyone be surprised if the agencies are themselves running bots, algorithms and accounts to affect visibility of discourse on threads like these?
      • beedeebeedee 1 hour ago
        That could be, but you should also be aware that many people will have the knee jerk reaction to reject statements like yours as being paranoid and delusional. Assuredly sometimes that is an appropriate response, but the drive to immediately reject narratives like yours is to protect ourselves from the doubt that validating your story would elicit. We do not want to believe those things are happening to those around us (even if we accept that they might be in general), and that is a fact that these organizations take advantage of. I wish you luck either way. Stay calm and suspend belief. We are human, and not only do we not know most things, the most important things we cannot know. You can build a composure that allows for many things to be true and not fully know which and still proceed. Otherwise you might be racked with doubt about who and how things appear and have trouble moving forward from this.

        How can you tell the difference between an algorithm and topics genuinely being consistently unpopular, though?

        > Would anyone be surprised if the agencies are themselves running bots, algorithms and accounts to affect visibility of discourse on threads like these?

        On HN specifically? Yeah.

        On actually popular platforms? No.

        • direwolf20 1 hour ago
          I run a HN voting algorithm and opinion manipulation system across a few hundred accounts - only a few on any individual post. I use residential proxies to prevent correlation. The account I'm using right now to confess this to you is one that's already been burned.

          Downvoting this comment is funny, because it's a burned account anyway, so not hurting me, and you want less people to know this fact about HN?

            • Karrot_Kream 25 minutes ago
              Try it, it's really not that hard. I feel bad saying this and I don't do anything like this anymore but I did make a few accounts behind residential IPs that posted HN popular sentiments on topics that were actually factually incorrect and got a lot of upvotes pretty quickly. I stopped because I felt icky with how corrosive the whole thing could end up being. This was a while ago so not sure if new user sign up has become more difficult.

              It turns out that open web forums are mostly emotional places and often the most inflammatory or in group opinions rise to the top. With that knowledge, manipulation isn't that tough.

    Same stuff different day. The United State's laws do not allow for direct domestic spying or something to that effect so they use Five Eyes anglosphere intelligence alliance marketplace as a loop hole. Since Reed Elsevier plc aka "RELX" has purchased LexisNexis who had purchased Seisint, Inc and the technology for Flordia's Multistate Anti-Terrorism Information Exchange Program "MATRIX", which was shut down due to privacy concerns by congress, it is only logical that the data aggregation technology is being used in full force now. There seems to be no other way but to allow 100% technology and communication introspection by the government to stop terrorism.
