"I'd consider this public pollution caused by extremely greedy billionaires ruining the planet."

This is such a weird framing, as if Starlink was a frivolous project for some rich person's fun.

There is genuine demand for orbital ISP from people, including people in poorer countries whom a better connectivity may help improve their incomes and lives, where an alternative is basically impossible (you won't get optic fibre in the Himalayas or Papua or the Andes anytime soon, if ever).

20 million people are now using Starlink and that number will almost certainly grow to maybe ten times as many, eventually. Ukraine uses Starlink to defend itself from being devoured by an aggressor. Sailors and other people in far away places use Starlink to keep in touch with their families.

Did you know that before Starlink, the South Pole Base had just 2x256 kB connection for everyone?

I get the "pollution" angle, but not the "hey, one guy is ruining the planet" angle. At the very least, all the customers are complicit, and I would add all the governments that don't seem to be able to build terrestrial connections for their own population.
