SpaceX is the only major operator of spaceflights in the US: more than 95% of all satellites launched are launched by SpaceX, not just in the US, but worldwide.
We have regions where we deliberately minimize light pollution, but those regions aren't immune to Elon's swarm of photobombing satellites.
Not that I don't think it's cool to have a web of spacecraft enveloping the planet and bringing high-speed communications to everyone everywhere - it's pretty impressive to point up and show a train of satellites to a kid - but astronomers have been complaining about them and they are right.
