Why Nostr is better, at least so far 👇 “Your phone isn’t secretly listening to you (at least in most cases). It's also not reading your thoughts... The real reason ads feel that creepy? Honestly, it’s worse. Let’s talk about how digital ad profiling actually works. Platforms track what you do. Every search, click, like, pause, scroll is logged, analyzed, and fed into systems designed to predict what you’ll do next. This is not a conspiracy, it’s their business model. But what about those moments where you only said something out loud or thought about it, and suddenly see ads for it? It feels like proof your mic is listening. It isn't. It feels like they're inside your brain, and they kind of are… The prediction engines used by these platforms are built on years of data. These systems don’t need to hear you. They already know you well enough to guess what you’re about to want. And quite often they guess right. Think about how much data gets collected: - Browsing - Locations - Social Networks - Things you almost do... Even the timing of your behavior matters. Compared with all of the rest of the stored information, this makes for a powerful predictor. Now let's zoom out. This data isn’t siloed off, it’s connected. Tracking follows you across apps, sites, and devices, stitching together a surprisingly complete picture of your life. Behind the scenes, a whole ecosystem makes this work: - Platforms (collect behavior) - Advertisers (buy attention) - Identity providers (link your devices) - Data brokers (buy & sell your data) Data brokers are especially wild. They gather info from countless sources, bundle it into profiles, and sell access to “you” as a product. … Advertisers don’t just target demographics anymore. They target probabilities: “People likely to move soon” “People feeling financially stressed” “People about to make a big purchase” You’re not just categorized, you’re predicted. So when you see an ad for something you just talked or thought about? This isn't your phone listening or actually scanning your brain. It's likely just the system realizing, based on everything else, that this was the next logical step. Put it all together and you get something close to a surveillance machine, a digital advertising panopticon at global scale: - Constant tracking - Cross-device identity matching - Behavioral prediction - Real-time ad auctions If it feels dystopian, that’s because it is. Not because your phone is secretly recording you… ...oh no, it's way way worse than all that... …it doesn’t need to.” — posted by Proton VPN on X
