alt Hacker NewsIt is very much a valid argument. SpaceX has been working on this issue for years.

FTA: "SpaceX has done a lot of engineering work to make its Starlink satellites fainter. They are still too bright for research astronomy, but thanks to new coatings, their brightness has not increased dramatically even as SpaceX has launched larger and larger satellites."
I acknowledge there's an issue here, but I don't think it makes sense to label it "pollution". When something is polluted it generally means using it can lead to some form of harm, directly or indirectly. I fail to see how confusing satellites for stars stars causes harm, per se (though of course it would suck to be an astronomer).
