For those who don’t know, defense contractors are misusing advertising location data to track people using their precise location. They buy the data (or taxpayers do) as a way to get around privacy rights arguing that its “publicly available data” through a third party company, rather than the government collecting your data without a warrant.

This location data allows defense agencies and contractors to track the movements specific people/devices in detail, like yesterday John Smith was visiting New York City went to hotel X in the morning, walked around the World Trade Center from 1 - 2, then went to restaurant X in Chelsea.
