The author isn't rooting for T-Mobile to die. He's pointing out that playing this game is capital intensive, and not making a lot of money is a long term liability when it comes to having capital to invest in your network.
He's probably not wrong. T-Mobile got a huge boost in the short term from all the cash and spectrum they got as part of the breakup of the merger with ATT. It was a whole year of CapEx ($3-5bn). That let them build out a kind of competitive LTE network. But that's a one time thing. If they continue to lose money, they won't have the capital to play the LTE+1 game.
