Astronomers, amateur or otherwise, have been complaining about "light pollution" forever. Traditionally, it's about night-time lighting on Earth that isn't shielded from transmitting light upwards.
It startled me to find (in a long ago HN thread) that people, presumably nerdy types, are not generally sympathetic to the complaints. I somehow assumed that universal lukewarm quasi-environmental feelings would mean people would go "yeah, lighting the night sky is inefficient and dumb, and astronomy makes pretty pictures" but apparently "fuck astronomers" is a popular opinion.
