Edit: This is a sincere question. Several comments on this story indicate people don't believe there's any regulation as to what happens in space.
Edit 2: While I'm editing things, here's the FCC Record for the original Starlink proposal in case you're curious what some of the objections brought up during the original comment period were. https://docs.fcc.gov/public/attachments/FCC-18-38A1.pdf Mostly it looks like other satellite operators worried about interference, orbital debris concerns, and there was a note about potential impacts on radio astronomy.
Astronomers are in other countries besides the US... and these satellites are going to span the globe impacting everyone everywhere.
Certainly people can complain that current international treaties, federal regulations and so on aren't sufficient, that the decisions reached by regulatory bodies were incorrect, or ill informed, etc. But first they should be aware those decisions existed and did take into account input from a variety of sources, and it's not just 'if you can get it to space, do whatever you want'.
Secondly, the problem is not just in federal air space.
The optical astronomers weren’t in the habit of commenting on satellite launch licensing and got caught on the back foot. Now the media campaign is basically optical astronomers complaining that “there is no process” because they didn’t get involved in the process in time.

That’s great because apparently nobody but SpaceX has any say in what happens.
