I can't bring a big European tech company to mind for any purpose not just this topic... there just hasn't been many influential consumer tech companies coming out of Europe recently that would have a big interest here. And as the article points out it's largely the consumer ones complaining here as the industry/government tech companies have already been under this level of regulatory scrutiny in the past, it's only new to consumer products.

So your argument seems to be built on a faulty premise that the two geographic industries are comparable yet one is silent... one is largely silent for another reason.

This is a bizarre and false statement. U.S. companies have been selling technology to Chinese companies and consumers for decades.

Routers (Cisco), farm equipment (Caterpillar), software (AutoCAD, Microsoft, Oracle, etc), medical devices (GE), factory equipment (GE), microchips (AMD, Intel, Qualcomm), high-precision measurement (Agilent/Keysight), etc.

The list is absurdly long. Your agenda is preventing you from seeing a more balanced view of things. Try to read a bit about cooperation between the two countries, such as huge foreign investment in Shenzhen, exchange programs between Chinese and American universities, success of Chinese technology firms in the U.S. (Huawei, Nexus 6P; Almost all solar panel companies; etc)
