The national security threat is purely hyped up because western companies spy on you for western intelligence and allow western intelligence manipulation of the feed of someone in the US or Finland but also importantly allow spying on and manipulation by psyops of someone in Vietnam, in Cuba, in Russia, in China, in Africa. Chinese companies will not do that. They will not give them global back-doors. They will cooperate to the extent required within the US or other NATO nations on spying on their users or manipulation as required by law but they will not allow global manipulation and dominance which is what this and the freak-out about Chinese 5G is all about. It's about making sure western intelligence controlled software, platforms, hardware is the global standard to compromise everyone everywhere, not about keeping the west secure from spying or influence.
