The CEO of T-Mobile's parent company, Deutsche Telekom's Timotheus Hoettges, said this week that the carrier's 'un-carrier' shtick is not sustainable long-term.

Unsurprisingly, outspoken T-Mobile CEO John Legere had a response to that: "It's total bullshit."

Hoettges told Re/code that they did "what [they] had to do" for T-Mobile, but left no secret as to why the carrier is always up for sale.

"The question is always the economics in the long term…and earning appropriate money," he said. "You have to earn your money back at one point in time."

Entertainment vs. information

Legere's outburst in response is entertaining - as his outbursts always are - but it would be nice to hear something a little more constructive regarding why the CEO believes Hoettger is wrong.

Legere has yet to follow up, so for now we'll have to take his statement on faith and continuing enjoying all our wonderful un-carrier perks - while we still can.
