It's naive to think that every country that supplies you with goods and you are at war with would go down a route like this. Is there really a single country you'd expect not to sabotage goods you buy from them if you continuously rain rockets onto their population?
I think the point is that, whatever probability a potential target would have placed on this sort of thing yesterday, those calculations have shifted now. Previously it was more abstract and something of this scale and physical attack would have been little more than a thought experiment. If a news pundit on Fox or CNN last night had been claiming China was doing this with Huawei phones then many people would have looked at it as fear mongering while of course knowing China has in all likelihood setup other supply chain attacks. Today it would sound a lot more likely.
