Starlink Satellite train
Plodding across the Atlantic this morning I was absent mindedly staring out the window enjoying the view as slowly but surely my eyes adjusted to the Milky Way coming in to view. A couple of nice shooting starts. And then a satellite passed overhead. And then another. And another and another and another and another. I stopped counting after 20.
After my post flight snooze I googled and found this.

At first I was impressed by what I saw. But after seeing as many as I did I was a little disappointed because it started distracting me from my usual favourites of Orion in all its glory.
60 was distracting enough. Then I read on 12000 of the blighters!!!! I’m all for the advancement of life and knowledge on this blue marble. And the internet is a powerful tool for knowledge. But are we going too far???

When the company launched its first set of Starlink internet satellites in May, those with their eyes attuned to the night sky immediately realized that the objects were incredibly bright. Professional astronomers worried the satellites would interfere with scientific observations and amateur appreciation of the stars."That first few nights, it was like, 'Holy not-publishable-word,'" Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, told Space.com. "That kind of was the wake-up call."

Whilst it's admirable (or malevolent) for the companies to want global internet for all, by further cluttering near-earth space with hundreds and potentially thousands of satellites seems counter-productive to my simple mind. I wonder if the mathematicians can quantify how much higher the chances are of collisions between said satellites and others of the same genre and all the space junk that litters Low Earth Orbit. I realise that Space is big, even that which surrounds us, but adding to the mix just seems like madness to me.
The crazy thing is that there is no control or oversight over the launch of satellites. It's a purely commercial thing - anyone or any business can send up as many as they can afford. The only regulation is of the frequencies they can use to communicate.
I don't see why they shouldn't be controlled as strictly as airline operations.

I think (from memory, from something I vaguely recall reading) there are agreements about the positioning of geostationary satellites, with them being allocated a "box" to operate in. Other than that - ?
Geostationary broadcast satellites are positioned according to area coverage and frequency coordination.
I'm aware of that, but I also thought (possibly mistakenly) that I had read/heard that because that piece of "real estate" was of such value there was an agreement/coordination system to try and ensure such satellites (and of course it's not just comms sats) remained in an assigned "box" whilst they were operational and that once they became "inop" if possible they were moved out of the geostationary belt.
I'll see if I can find out further...
Edit to add: here you go:
There's a Parking Problem..

But there is no control for all these new satellites that the OP refers to, other than frequency assignments.
There could be even more:

If thousands of these craft are sent aloft, what's the chance of damage to Moon or Mars mission craft, probe launches, or even future satellite launches?
But SpaceX isn’t alone in its satellite broadband ambitions: An international consortium called OneWeb is aiming to put its own broadband constellation into space with more than a billion dollars in backing from Airbus, SoftBank, Virgin Group and other partners. OneWeb’s first launch is expected to to occur within the next six months.

Apparently SpaceX is considering this issue and are investigating less reflective coatings for the starlink satellites. This will not help with the space debris problem of course, but it makes sense for reducing the effect on astronomy.

StarLink will have been blocking it from view
But when there's money to be made, who cares about shutting down astronomy? Look at all the trouble those pesky scientists have been making over CO²

The astronomy problem can be solved relatively simply.

Being done already with certain types of less well-publicised satellites... if you catch my drift.
