You are being uncharitable. There is nothing misleading about this, or any other, nightsky timeseries image. It claims to show the paths of satellites over 2 hours, and that's what it does. You have to edit things like this to reveal the signal and keep relatively constant elements from overwhelming the result. Astronomers do this exact same thing (erasing things that obscure the subject over time).

Even if I were to be as charitable as possible to your interpretation, "mendacious" is way too strong a word, and implies an unreasonable bitterness.

I don't understand. Are you laboring under the impression that the artist is trying to convince people that this is what the night sky looks like at any given moment? What even are you upset about?

It did say he was a photographer, not an astronomer.

Surely an astronomer would have software for this that would produce a more accurate picture.

The photographer was completely transparent about how the image was produced and what it means.. how you manage to color this as dishonest is beyond me.

The point of the image is to make a point. Art is provocative. Our skies are choked as anyone who makes Astro images will tell you.

It’s called art.

Has he not heard of AI?

Its parameters are very well described and the result is beautiful (visually), interesting, and provocative. Yes, people will misinterpret all sorts of things like this, but I don't know what else the author could have done besides not create it at all, for fear of... these accusations?

Ironically, the same technique used to remove the stars and isolate the satellites could have been used to remove the satellites and isolate the stars.

It would take 100X less effort to remove the satellites.

LEO will be worthless soon enough.

Technically it is a limited resource, since there is only a finite volume. But we're nowhere near close to any notion of it being "full." Efficient rent would be approximately zero.

To whom would they pay 'rent'? What would be done with the money?

Don't go there, it leads to nothing but more waste, abuse and corruption. If it becomes necessary there can be some form of arbitrage in how LEO is used, we're not there yet though. Maybe something like the auctions for bandwidth for mobile operators but again, where does the money go? If institutionalised it will just turn into another slush fund for whatever interests, many of them corrupt or nonsensical, to drain.

What makes it "ridiculous"? I can go outside and look at the sky for five minutes and see airplanes flying past, does that mean our air traffic is also ridiculous?

Of all the things to be outraged over... satellites provide extremely valuable services and are pretty near harmless. There's the pollution from the launches, some uncertain concern over putting materials into the upper atmosphere when they reenter, and that's about it. The thing people complain about most is that they get in the way of photographs of the starts. Which is annoying, but also seems to be easily worked around, and is pretty small potatoes compared to planet-wide communications. Your neighbor operating a leaf blower with a dirty two-stroke engine is harming you more than these satellites are.

Most satellites in low orbit are Starlink, and most Starlink satellites are at either 43° or 53° inclinations, so it's probably those. These inclinations cover most of the population in the most efficient manner. Low inclinations don't cover people at higher latitudes. (Inclination is equal to the highest latitude that the satellite will reach, and then coverage extends a little further since they have some slant range.) Higher inclinations waste more time over unpopulated regions.
