A merger of Sprint and T-Mobile US will merely make this oligopoly less competitive because it would offer reduced choice to consumers. Instead of two highly motivated challengers to the market leaders, there would be one potential challenger (a very large No. 3) with no real incentive remaining having taken over its closest competitor. Softbank's interest in T-Mobile US has nothing to do with improving consumer services. It has everything to do with taking out a competitor. Softbank stated that it needs to be larger to compete with the "duopoly." Seriously? How about offering better services? T-Mobile US is doing so and winning market share. Clearly, T-Mobile US has its "mojo" back. The services they introduced recently and the energy they bring to the market are helping them gain market share.
