What they're doing to Huawei will have nefarious consequences to the US. Who can ever trust a country that can use this kind of tactics to destroy a comercial competitor?
I suppose the only real difference was that this wasn't well-known in advance. It's like the Joker's statement about people losing their shit when something happens unannounced but being orderly when much worse is announced in advance.
And what consequences do you imagine there will be?
Previously, my little factory spent 100% of the budget for component x and component y on buying from American suppliers (quality and price are both very good).
But going forward, we plan to spend 70% to buy from Americans, 20% from other countries, and 10% to fund demestic research, and we will reduce the 70% part as soon as we can manage.
You can imagine if multiplying our small adjustment by the actions of hundreds of thousands of similar businesses around the world who are watching closely what's going on recently, then the interests of American businesses will probably be severely affected.
