Algorithmic price discrimination. Starbucks tracked former journalist Geoffrey Fowler’s shopping habits and clicks, selling this data to over 60 third parties to adjust his rewards and pricing based on his perceived addiction to caffeine (The Preamble). Walmart filed a patent for technology that dynamically modifies prices for items like mayonnaise based on other goods already placed in a user's cart. Expedia and Booking.com exploited IP addresses as proxies for wealth, listing a New York City hotel room at $800 for San Francisco users while offering the same room for $318 to users in Kansas City.

Meta illegally collected and processed sensitive health information, including menstruation and ovulation data, from millions of Flo application users between 2016 and 2019 (Offline, With Alison Rice). OpenAI’s AI agents inadvertently exposed private user images to external hosting sites without the company’s ability to attribute the leaks back to specific owners. Elon Musk’s Grok AI produced an estimated 3 million sexualized images in 11 days by digitally undressing photos of women without their consent. Texas authorities previously stored over 5 million newborn blood spots without parental consent, eventually providing 800 de-identified samples to an Armed Forces lab for a national DNA database (Courage & Caffeine by Rebekah Ricks).
