Clearwire's new chief John Stanton in an interview Thursday voiced his objection to the proposed AT&T buyout of T-Mobile. He cast the company's potential 79 percent control of subscription customers in the US as a "huge challenge to competition." Device exclusivity was already a problem with AT&T, such as its recently ended iPhone exclusive, and could only get worse if the carrier had that much more clout, the CEO told the WSJ.
