Sprint is not interesting in taking on an even more powerful competitor in the battle over mobile market share. The company formally filed a petition with the Federal Communication Commission to block AT&T's ultra-huge bid to acquire T-Mobile for $39 billion. This, after Sprint verbally complained to the FCC about the muscular move, claiming that AT&T's purchase would "would entrench the duopoly" meaning "the rest of the carriers in the U.S. market would be small in comparison." The formal complaint uses the same language to describe how the telecommunications industry would be backpedaling in approving such a large merger. Sprint said of AT&T and Verizon, "The Twin Bells' market dominance would dwarf Sprint, the sole remaining national carrier, and the rest of the wireless industry, thereby creating an entrenched, anti-competitive duopoly."
At 377 pages, Sprint's complaint document is both thorough and impassioned. Highlights include a section called "Alice in Wonderland"--note the imagery for the the "small in comparison" statement!--which undermines AT&T's argument for fairness citing "dire capacity constraints" in its application to the FCC. AT&T's CEO earlier this year boasted that they're "really starting to feel good about the network situation."
