Earlier quoted context omitted.
Sprint was cooked for one specific reason: parent company QWEST refused to do the prism-split of fiber cables into secret NSA colocation rooms like AT&T did.
Qwest never owned Sprint.
In March 1998 Qwest announced it would acquire long-distance carrier LCI International Inc. for $4.4 billion. The deal created the fourth-largest long-distance carrier in the United States behind AT&T, MCI Worldcom, and Sprint Corp. The combined companies had about 5,800 employees and revenue of $2.3 billion. The acquisition gave Qwest 2 million long-distance customers and a well-established sales force.
