I know a thing well: smartphones do serve very well for deep and spread surveillance. They are almost substantially mandatory (many banks in many country mandate their own app for web auth, for instance) and they are macro-spy instead of micro ones, that instead of being payed bye the one who spy are payed by the one that get spied who also ensure proper power and connectivity. Other side effects are far, far less relevant...
