Bashing the RootMetrics report, Legere was quick to respond, using barnyard language:
RootMetrics released this statement to CNBC, which read in part:
"We don't typically get involved in back-and-forth commentary between CEOs, and they have no influence on how we conduct our testing, how we analyze the data we collect, nor on our final results. ... We stand by our methodology and our results."
On CNBC's "Squawk Box," Claure said, "We just don't like it when somebody insults Sprint. I guess someone like John Legere, we have to talk to him on the same language and the language he understands and a language he uses pretty well."
He tweeted a meme with Legere's photo Monday night, playing off the Universal movie "Straight Outta Compton." Legere responded Tuesday morning. (Comcast owns NBCUniversal and CNBC).
Legere also tweeted about this article later in the day:

Two weeks ago, Sprint reported a smaller-than-expected quarterly loss of a penny per share and raised forward guidance. But revenue was short of forecasts.
In a race for subscribers, Sprint, which posted 57.7 million customers at the end of the quarter, slipped to fourth place among U.S. wireless carriers, falling behind T-Mobile, which reported 58.9 million customers for the period.
Hopes were dashed earlier this month, as the long-anticipated prospect of a merger of Sprint and T-Mobile was scuttled, due to what's perceived as a unfriendly regulatory environment.
