Well, if there really are concerns of privacy with Huawei, the US can prevent their equipment from being used in 5G (Already done, it's very protectionistic and unjustified but OK) or even prevent Huawei phones from being sold in the US. (Even more unjustified, but whatever)
What is a frontal attack on market freedom is preventing all American companies from doing any business with Huawei, just like that, overnight, because of a whim of the Trumpturd.
No matter how people spin it, this is war on international trade, and it's hurting American companies as much as it does Chinese ones, and creating huge collateral damage on top of that.
