Those are revenue figures.
> This hits everyone. And it’s not a serious cost issue.
That it affects everyone just makes the problem worse. If China or the EU does commit to a starlink competitor, there's even more crowding in orbit. Even more collision avoidance required.
> Starlinks are still being deorbited before they need to be due to obselescence
That's the point. These things are not staying up long, and they're staying up shorter and shorter.
The constellation is both expensive to build and to maintain. That makes it a lot of trouble compared to running a bunch of fiber once and having only occasional maintenance trouble when some idiot drags a backhoe through it.
> Infrastructure gets blown up and shut off. Hence the military interest.
The military interest is real, but it remains to be seen how much money they're willing to put up for it. Higher latency more conventional satellite internet will have significant cost savings in comparison.
And also net income.
> just makes the problem worse
Did you skip the part where it’s not a serious cost issue? None of these birds are even close to being propellant restricted.
> These things are not staying up long, and they're staying up shorter and shorter
Because they’re being intentionally deorbited to make room for better birds. They don’t have to be deorbited as quickly as they are. But overwhelming demand makes it a profitable bet.

$70mm per year for 22 birds [1].

The cost isn't in paying someone to not use the orbit, it's that the busier a part of space gets, the more expensive it becomes to do collision avoidance and station keeping.
What makes this impossible to calculate is that there's an unknown exponential involved. The more satellites, the more collisions that need avoiding. And the higher the chance that one avoidance will create new future collisions.
At some point the space is simply so busy that collisions can no longer be avoided.
It’s really not impossible to calculate, particularly if you’re trying to cause damage.
The answer is it’s cheaper to shoot down individual satellites than try to create a localized cascade. Kessler cascades propagate too slowly, and degrade too quickly in low orbits, to be useful as a military tactic. In high orbit one could feasibly e.g. deny use of a geostationary band. But again, it’s cheaper to just shoot down each satellite.
> For example, although the Starlink subsidiary reported $2.7 billion in revenue for 2024, the same financial statement doesn’t account for the costs of launching and maintaining a fleet of nearly 8,000 Starlink satellites.

Those figures, to my understanding, include cost of services and launch in COGS.
