Why does it have to be a deep space image? We could look at local space earth or the moon? Even things in our own galaxy would look cool.

Ever play Pac-Man? They are launching a large Pac-Man that will go around the earth and gobble it up

Most of the stuff in lower orbit is government research satellites and dead stages (by mass).
Commercial is generally higher geostationary orbits.
"The wealthy" you mean SpaceX are relatively new and are able to self deorbit.
There is some commercial activity in the lower orbits that has not deorbited, old Iridium and so on.
This is not really crowdfunding its investment funding.

100% yes.
What scientists and computer modeling has discovered (theorized) is that binary systems in general are far more common than solitary ones. So binary stars, binary planets, binary moons (binary here being objects which orbit around one another and their center of mass orbits around another body).
You can see this in models yourself too. For instance, the game Elite Dangerous simulated the entire galaxy by using their stellar forge algorithm. Obviously its a game, so take that as you will, but they used a lot of real physics in creating their algorithm for the Stellar forge. And you will find many star systems have binaries all over the place.

Good luck to them but I am not really clear on the business model.

Which was also the name of a pretty cool comic book back in 2014 or 2015

You don't. You catch it, heat it with mirrors and lenses. Smelt out the metals. Radio tag for recovery, leave iit at L4.

This is good, I wonder how they'll actually de-orbit the debris?

And btw anything living on a planet system like that wouldn't be to happy given the crazy geological activity.

Yes, it is possible. It's highly unlikely that they'd be the same, like most women's boobs. One is always a little bigger than the other.
Here's the thing that no one else here has mentioned -- The orbits of two similarly sized objects around each other (such as Venus and Earth), while also being in orbit around a much larger object (the sun) is much more stable if the planet's orbits around each other is in the opposite direction as their orbit around the sun. (clockwise and counter-clockwise, for example.)
That's how the math works, but weirdly, there are no examples of counter-rotating natural satellites in our solar system, even though they should be more common.
There is still much we do not understand in the universe.

It's how every startup works. They aren't crowdfunding like a kickstarter, these are already wealthy people investing money because they hope the concept will take off and earn them many times what they contributed. Why have existing companies clean up their own mess when you can create a new company to get paid by existing companies and take a slice of that pie.

I’m confused, we’re now crowdfunding to get rid of all the junk the wealthy have put in orbit around our planet?

We had plans to do this in the 80s. This is ....hmm. how did you think we are going to mine the asteroid belt? You catch a rock, put it in an Earth crossing orbit, and refine it on the trip home. The energy is free, just lots of focused light. You set the asteroid in a slow tumble so it heats evenly. Return to Earth orbit with a few tons of refined metals and other goodies, probably already presold.
