On Monday, the Federal Communications Commission (FCC) announced that it is fining the top four mobile carriers in the U.S. for illegally sharing access to the location data of their customers without consent. In a press release, the FCC claimed that the carriers failed to protect the highly sensitive information that their customers entrusted to them.
Specifically, the FCC claims that Verizon, AT&T, T-Mobile, and Sprint (prior to the merger of the latter two) sold access to customers' location data to aggregators.
