The quote you cited was not an example of scientific collaboration or espionage. In this case, yes, the espionage probably endangered someone's life, given China's human rights track record.

I see your point, though, and agree that science collaboration is not harmful. However, I think that the article was mainly focusing on Chinese military advancement, as most of the attacks cited in the article were on our military infrastructure. Again, I would say that a more advanced military will endanger people's lives.
