Well the issue is that not everything is black and white.
On one hand, these satellites can potentially absolutely wreak havok on astronomy, and our own view of the night sky. Nobody wants that.
On the other hand, in a few years, these satellites are able to provide cheap internet all over the planet, which would allow poor remote communities in South America, Africa, and Asia access to the internet, which is practically impossible through any other means. IMO, its worth the tradeoff. I think helping people is more important than astronomy, but I recognize that that’s just my opinion
