The bill will likely face pushback, as selling user location data is big business, and not just for bounty hunters. According to The New York Times, selling location data generates billions of dollars per year for telecommunication firms and mobile app companies. But recently, the practice has been scrutinized. The FCC called for a federal crackdown, and major US carriers have vowed to stop selling location data.

Not wanting to wait federal action, some cities and companies are taking matters into their own hands. Los Angeles sued the Weather Channel app owner over "fraudulent" data use. Google now lets users auto-delete activity and location data, and iOS 13 will show users where apps have been tracking them. It's not guaranteed to pass, but the New York City bill could be the first in a trend of cities establishing their own location data rules.
