There is also the (no help at the moment) fact that the more money that Starlink's parent company makes, the more likely we are to get the world's cheapest heavy lift orbital booster soon, and the more likely we are to soon have multiple large orbital telescopes that far exceed ground-based capabilities.
Basically, if SpaceX makes it, we'll probably have a Starship-launched lunar observatory quite soon, in the grand scheme of things.
This doesn't help the situation now, although there is so much screaming from the anti-Musk people as well as the pro-Musk people that it's hard to tell what the actual impact of the now-somewhat-albedo-mitigated starlink v.whatever satellites are. All of the coverage is breathless sky-is-falling stuff.
In any case, the situation is temporary. Either SpaceX makes it and we get a far side of Luna observatory and LEO/MEO telescopes besides, or they don't and in a few years Starlink all falls down and burns.

Right in the middle of the window and it actually seems to be doing a pretty good job of threading its way around the world while minimizing encounters with landmass - by pure luck of course.
