"Light pollution" for naked eye viewing of the sky is not a big concern for Starlink anymore. SpaceX has designed a sunshade which should make the satellites completely invisible to the naked eye in their service orbits. The sunshade has been designed in collaboration with astronomers to ensure that even the most sensitive telescopes will not have problems with it either.

Will the Chinese do the same? We'll see. But it's definitely possible to mitigate these concerns. There's not much to discuss until a credible competitor to Starlink emerges.
