Default CNN article on problems in Air Travel, as seen by FAA

That's like saying a Ford F-150 pickup truck can't be used as a ski
boat because Ford deliberately designed it that way.

Not quite. The GPS is a receive-only system. It allows users to determine
their positions without transmitting anything to anyone, which provides
stealth and also gives the system unlimited user capacity. There isn't any
way to get a transmission function out of GPS. All tracking systems are more
complex systems in which GPS merely plays one part.

This was all by design. The DoD wanted the capacity and didn't want their
troups to give themselves away every time they checked their positions.
