What goes around comes around
When you go around shrieking about how a Chinese company puts your comm infrastructure at risk without any proof whatsoever, and try to strong-arm everybody else to "trust" you just because, well you can hardly be surprised that China, in turn, takes your arguments at face value and sets its own comms infrastructure rules down.
Except that China doesn't have to go shrieking that Cisco is beholden to the NSA, everybody knows that - and there's proof.
