True to form, T-Mobile CEO John Legere has started his press conference by roasting every one of his major competitors, all while holding a Red Bull. Legere has been outspoken in his distaste for other carriers — a name his company has ostentatiously rejected — and today, he attacked ATT, Sprint, and Verizon for bad service, high prices, and generally being uncool. I give Verizon huge credit for admitting their network is overloaded, he said. But in this industry you should be able to leave if the network doesnt live up. He mocked Sprint for asking customers to pardon our dust as it upgraded its network: Sprint is a pile of spectrum waiting to be turned into a capability, he said. But neither of these carriers have anywhere near the sustained antagonism that ATT does with T-Mobile.
