Biggest reason is mass. If you've got a couple of 60,000 lb-thrust engines and the fuel budget of the Air Force then the extra mass won't matter too much (military equipment is heavily shielded and can tolerate EMI). But if you're Joe Somebody, you won't want to pay the $50 extra dollars for fuel so Jim Businessman can call the office before landing.
