They provide an excellent service. They're a minor hindrance for astronomy, true, but I think it would be hard to make a good case for that a few people having a good view of the sky is more important than millions having good communications.
Then there's that there's nothing really special about Starlink. It's merely one of the first users of cheap rocket launches. It could be somebody else, or 1000 different entities launching smaller numbers, in the end the effect on astronomy would be the same.
