I am not coming out against The "Dark Sky" but sometimes bright lights are fun. If I were a DT resident I would want to see the stars. In some cities they shine the lights up on the buildings and it feels more vibrant. Granted those down towns may have just been more vibrant is why I felt that way.
I think you can have both. Decorative lighting (Fidelity) and accent lighting don't have to cause light pollution. This study looked like it was mainly addressing street lighting, which should Light the Street. The article was arguing against light pointed up at the sky, which serves no purpose.
