T-Mobile CEO John Legere talks a lot of smack. On stage, he’s a cyclone of cursing and boasting, snide remarks about the competition, as well as a complainer and apologist for T-Mobile. The company he leads seems to need all that help, too. As much as Legere brags up T-Mobile, signs of just how limited their service really is peek out now and then. In asking the FCC for more spectrum at a better price, T-Mobile is also admitting they’re not very competitive — but not humbly so.
