China stealing German/European technology is a common topic here in Germany. HN is just a relatively US focused site, so it isn't discussed as often here.
I'm Chinese, and I can tell you there are many people in the dark corners of China's Internet are talking about similar kind of things: Spy stories, military secrets, dark politics & histories, rumors etc. Basic human nature. But if you don't read Chinese and look into the right place, you'll simply unaware of their existence.
I don't think all English speakers can also speak or read German, so maybe that's the reason, rather than "They just don't care".
Maybe it's language related.
