ThirdShifter It’s probably data that they’re exposing within the public pages or publicly accessible APIs. If they don’t want it publicly visible, they shouldn’t be making it publicly exposed.
I remember when somebody made a browser extension a couple years ago for Verizon and AT&T that exposed the hidden mmWave layers both carriers had on their coverage maps. AT&T “fixed” theirs by removing the layer from their public maps. Verizon’s remains functional and can still be exposed with the extension.
