As someone who worked and briefly lived in subsaharan Africa, I will say that the advantages are huge. Bandwidth alone isn't even the whole story - latency really matters too, another area where Starlink is super helpful compared to say, trying to get fiber punched in west from the southeastern parts of Africa. I have not yet mentioned the benefits of state actors not being able to cut your fiber at sea where nobody can see them.

This is a pretty uncharitable take. Every largish construction company in the country uses StarLink for their many projects where Internet isn't available. Yknow, actually building the country out. It's a game changer.
