The wireless industry has been under Washington’s microscope all week, and the posturing politicians aren’t goint to ease up any time soon. Most recently, some whining senators have prompted an FCC inquiry into handset-exclusivity deals. While there are real problems here — the plight of rural carriers, most notably — attempts to ban such agreements are simple-minded and, ultimately, wrong-headed. Would the Beltway do-gooders force Verizon to support Apple’s App Store, which cuts carriers out of download revenues, in order to offer the iPhone? Or, as Stacey at GigaOM asks, will they require OEMs to build several versions of each phone to support various networks, raising the price of handsets? Crusading against big business plays well with voters, though, so don’t expect the governmental activity to just fade away.
