The problem here is that the USA government thinks that it is above the rules of every other nation on earth. When any other national government pursues the same actions as the USA government, you really cannot complain unless you complain about them all.

So back to the point of the Chinese appropriating knowledge for Chinese use, unless you want to complain about the USA government leading the way in this area, there is nothing to complain about.

You might not like it but if you want to say there is a "moral" difference between the actions undertaken by both governments, you really are on very thin ice, so to speak.
