It is unfortunate but the situation with Huawei is a matter of great FUD. On the one hand, they probably are dodgy as any organisation & in league with the People's Liberation Army. The major risk they pose is doing precisely what the the US is doing with their spy network and the risks of that are well understood.
But on the other hand, while this may be a real story, but it is just one thread of a bigger story where the Asia keeps challenging the US's high-tech edge. CNN + the FBI is not a combination known for fair, honest and reasonable journalism and this could well just be stirring up muck, trying to discredit a superior Chinese solution.
