The GP is referencing the Holocaust since the story is about Germany. Though I don't know what that has to do with this article or the comment he is replying to.
> Some European countries, only very recently cared more about insects than people
Is not a "us or them" dichotomy. The only possible alternatives are insects-win/humans-win or insects-lose/humans-lose. We can't have agriculture without insects.
Fun fact: they started to care (only), because it's going to affect people. The drop in insect populations has become concerning. Without them, no crops, no fruits, no agriculture, which isn't that great a prospect for humans.
How is it "more about than"? What are the costs to people by mandating dimming the light?
