T-Mobile Claimed Selling Location Data Without Consent is Legal - Judges Disagree (arstechnica.com) 23

A federal appeals court rejected T-Mobile's attempt to overturn $92 million in fines for selling customer location information to third-party firms. From a report: The Federal Communications Commission last year fined T-Mobile, AT&T, and Verizon, saying the carriers illegally shared access to customers' location information without consent and did not take reasonable measures to protect that sensitive data against unauthorized disclosure. The fines relate to sharing of real-time location data that was revealed in 2018, but it took years for the FCC to finalize the penalties.

The three carriers appealed the rulings in three different courts, and the first major decision was handed down Friday. A three-judge panel at the US Court of Appeals for the District of Columbia Circuit ruled unanimously against T-Mobile and its subsidiary Sprint. "Every cell phone is a tracking device," the ruling begins. "To receive service, a cell phone must periodically connect with the nearest tower in a wireless carrier's network. Each time it does, it sends the carrier a record of the phone's location and, by extension, the location of the customer who owns it. Over time, this information becomes an exhaustive history of a customer's whereabouts and 'provides an intimate window into [that] person's life.'"

  • Is there actually a law that protects consumers here? Aside from California, because I think they have something specific. It seems like whether this is considered illegal or not depends on the whims of whoever is currently appointed as judge.

    Cellular communication requires precise time, usually involving GPS. Cell towers have to know more or less exactly where you are for communication to work efficiently. Who you are and where you are are "their" data by this line of reasoning. It's something that sh

    • Indeed. Their fix will *not* be to stop doing it. Instead, they'll send an updated TOS that you must agree to, in order to keep doing business with them.

      Suggest reading the decision: https://media.cadc.uscourts.go... [uscourts.gov] It's pretty easy to follow, and it makes clear how the Court established what the law required telecom companies to do. IANAL, but I'd summarize the Court's summary as "Customer location data, whether or not they are actively on a call, is covered by this law. Therefore telcos, and companies they provide location data to, must have consent. There are a few exceptions where location can be provided without prior consent, particularly for emergency services/911 calls." The problem here was not directly T-Mobile/Sprint conduct, but rather conduct by companies that bought data from T-Mobile/Sprint. Some of those companies violated their contracts on allowable use. The FCC held that T-Mobile/Sprint failed to adequately monitor the terms of the contract to make sure the other companies were actually doing what they promised. That was particularly egregious failure after the bad practices by subcontractors were revealed in the press. So this was a 'failure to supervise/audit the terms of the contract'.

      • In regards to Consent, this is given in almost all apps that users install on their phones, gathering this data from 2nd and 3rd parties, to the consumer-telco relationship this judgment rules, on is what Palantir, etc... do

        • I dunno about Android, but on iOS there's a means to control whether an app has access to location data from the phone. I usually say "no."

          But that is clearly different from location generated by Telcos from cell tower data. That data is under control of the Telco, not the handset. The Telco, or agents using that Telco data, must have explicit consent, as required by the law, to use location data from cell towers.

            I've run into a few apps that won't install unless you approve of them accessing your location data. I generally allow it then remove the permission and they'll almost always continue to run.

        • Is it though? I'm not sure that I've seen a conscent declaration to *on sell* my precise location data in bulk. Read the terms in more detail. You may be assuming you're giving away more than you actually are.

  • I'm looking forward to the check for $3.18 that I'll be receiving in several years for this.

    They really need to take pilgrimage to the holy city on the hill and make an offering (preferably in real gold) to the high holy potentate for absolution.
  • $1million donation dinner. This ruling will then be toast thanks to an executive order a week afterwards.

If it's worth hacking on well, it's worth hacking on for money.
