Yeah it sucks, but I think it is kind of inevitable that someone was going to do this, and even Iridium had similar problems. Now that we have at least 3 companies pouring in serious money, it seems likely that the economics will keep pushing for it.

My hope is that this will lower the cost of access to space with another magnitude, which should allow a serious scale up of the amount of astronomy done from space.

I would also be glad, if you could just look at the sky and don't be disturbed by satellites and air and light pollution. I think, SpaceX and others will eventually manage to make the satellites less or mostly not disturbing. But lets face it, SpaceX actually enables better professional astronomy because launching a telescope into space is now much more affordable. Also all those remote locations, where normal earth based astronomy still kind of works will have a usable internet connection to transfer the results e.g. for computation and further instructions. Also scientists will be able to e.g. video-talk home which should make these long trips into nowhere more socially acceptable in their respective families. I can imagine, that would make some of that research more surmountable.

I don't think SpaceX would break Earth satellites. Isn't it trivial to remove a light streak from a picture? Satellites were a problem before SpaceX and I'm sure it's 1 click in some software astronomers use. The surface area of a streak of light must be less than 1% of the total surface area so virtually no information is lost. If you use multiple exposures it's even less. Seriously, an astronomer who can't deal with this problem should just give back their PhD. The idea that humanity should be prevented from extending internet access to the entire planet because an astronomer finds it too inconvenient to click a button is example of entitled behaviour on a scale I've never encountered in my life.

I prefer an orbital ring already across the entire sky.
