Sprint CEO Dan Hesse echoed some of those concerns in a letter to Clearwire last week, noting that the Dish deal is not a "viable alternative to the Sprint merger agreement." He also suggested that Sprint would take legal action if those rights were ignored. But in today's press release, Clearwire's special committee said that the Dish deal is in the "best interest of Class A stockholders." Sprint and Dish are fighting over Clearwire, the Bellevue-based broadband wireless company, largely for its highly coveted wireless spectrum.
