I’m supposed to “think of the astronomers” when billions of people will get cheaper internet and advance humanity? Astronomers can find ways around this, we can’t stop progress for 0.0000000001% of the population.
We should be trying to control our light pollution and space litter instead of increasing it, however. Seeing the galaxy with naked eyes shouldn't be alien to everyday people.
The reality is even quite poor countries are able to secure high quality internet for reasonable cost with appropriate policy. This isn't an otherwise unsolvable problem.
