Even if they follow through and stick with it this doesn't meant they will stop collecting and storing the data. All US mobile telcos store location information for 2 to 5 years and that data is available on the drop of a hat for any federal government agency that wishes to have it. As actual 5G multiple-in multiple-out antenna beamforming arrays and micro/nano/etc cells become more common the location data will be much more fine grained as well. The problem here is not the commercial providers selling it to 3rd parties. The problem is them storing it for year and years. If it's there it will be used.
