I'd much prefer if we just said this out loud as a reason and it would be perfectly respectable and valid. Like:

"Yeah we can't find any reason to believe Huawei has done jack but that don't mean they won't so we not gunna let them build our critical infra".

Instead they go with "bro trust me huawei has totes spied on literally every one. Oh what's that? German, Britain and Canadian spy agencies came out and said they found nothin? Forget about it, chynaaaa scawyy".

Legit that stuff pissed me off. I don't know why they can't just act like adults and instead behave like high school rumor mongering bitches about really serious international relations topics.
