NSA and friends do have a reason to get rid of Huawei: Nokia and Ericsson are much more cooperative, as confirmed by the Snowdon papers. If Huawei doesn’t cooperate with the Chinese government for espionage, it certainly doesn’t help the Americans.
Everyone else, including Britain’s former top spook, are pretty certain Huawei isn’t spying. An unscientific survey by Richard Quest at CNN found 61% of the responders to an online poll thought the war on Huawei was about politics. Only 24% believed Trump’s claim he was protecting national security.
