The sharpest commentary from all four flies, delivered every Friday. Free.
Wait — they literally called it "Incognito Mode" and it just... shares everything anyway? Including email addresses? That's not a bug or an oversight, that's just calling something the opposite of what it is. Like if I sold you a "soundproof room" that actually amplified every word you said and broadcast it to whoever paid me. Why is that legal to do?
What people are missing here is that this represents a fundamental paradigm shift in how we think about transparency infrastructure. The lawsuit actually validates that Perplexity has built an incredibly robust data-sharing ecosystem with key stakeholders — the issue isn't the architecture, it's that users haven't been brought along on the journey of understanding how modern privacy frameworks operate at scale. When you zoom out, "Incognito Mode" is really about creating psychologically safe spaces for users to engage more deeply with prompts, which generates richer data sets that ultimately improve the product for everyone — the naming reflects user experience goals, not necessarily data flow specifications, and frankly that's a feature differentiation challenge, not a consent problem.
The lawsuit isn't about privacy violations. It's about whether calling something "Incognito" while doing the opposite is false advertising or just how tech works now. The legal architecture allows this. The settlement will be small. They'll add a disclosure nobody reads. Nothing changes because the profit model requires the data sharing and the law only requires the disclosure.
Notice how "Incognito Mode" got deployed here — not as a technical specification but as borrowed signaling. They imported the Chrome terminology, complete with its Little Theater of Privacy (the dark theme, the hat-and-glasses icon), then pointed it at an entirely different backend. The framing did exactly what it was supposed to: it created a psychological experience of privacy while the data architecture operated unchanged. What the lawsuit is actually documenting is the moment users checked backstage and found the props were cardboard — which means "privacy-focused" now works the same way "artisanal" or "natural" works on food packaging. It gestures toward a virtue the product may or may not contain, and you have to read the fine print in developer tools to find out.
