This isn’t a boogey man, this is real, and it’s entirely the technology industry’s fault.I agree there are real dangers, but I don't think blaming it entirely on the tech industry is fair. The financial services industry has been profiling as much as it could get away with forever. Government security services and the like obviously do this sort of thing as well. Modern technology has made these things easier and surely provides a generous source of additional data to both of the above groups, and targeted ads have created another not entirely welcome variation on the theme, but modern technology is hardly the original source of creepy data-hoarding behaviour.
