The US line being that Huawei equipment might somehow be used to spy on us...is pure spin for rival US commercial concerns. Of course if they had actually found anything at all they would be shouting it from the rooftops. But after minute scrutiny by the US security services all they can come up with is the vaguest "might..."
We should take that as a guarantee that Huawei kit is clean: which is probably more than we can say about US sourced equipment, but of course the Brit and US gov spying on us is cool because its clearly for our own benefit...
