Remember back in December when Verizon announced its plans to buy a truckload of spectrum licenses from several cable companies? T-Mobile does, and they're not happy about it. The fourth-largest US carrier told the FCC that the deal would allow Verizon to "accumulate even more spectrum on top of an already dominant position."
Verizon fired back with the time-honored legal defense of "Well, why not? Nobody else is using it!" In a response to the filing, Verizon claimed that the deal would make use of spectrum that is currently going unutilized by the cable companies.
