Surveillance by corporations is also used for: - creating, maintaining and exploiting information asymmetry - manipulating markets, fostering rent-seeking - finding new ways of externalizing costs that escape easy detection - polluting honest policy debate - manipulating the democratic decision-making process - avoiding responsibility for malfeasance - etc, etc, etc, etc, etc and yet more etc
