This isn't a war. We can have both. If no effort is put in to make everyone happy, that's bad, so it's good they're working on these light issues.
So we can now have both. Africans can have their satellite internet, and astronomers can see their dwarf stars. Both should be satisfied so what are you so bitter about?
Well I'm not sure about that. There are 3 African countries where Starlink is available (unlike for instance every single country in the EU where both fiber and 4/5G coverage is quite decent already).
Also even in these 3 countries it's still prohibitively expensive for the majority of the population.
Starlink will definitely help provide internet for whole villages, or to remote cell towers. And distributing the costs may make them affordable. But my suspicion is that charities will donate hardware and then when support runs out, the villages will cancel the service.
You seem to assume that Starlink is the only solution to communications in rural Africa. There are other proposed satellite constellations. There is the traditional fiber optics and cell towers. Starlink in the US is successful because of the failure of government and companies to run lines to rural customers. Most importantly, those options are available if Starlink doesn't work from light pollution.
