I'd bet there's also a bit of geopolitical planning going on here as well. It will be far easier to cut african nations off from the internet if we control their access points.
As with every gift from the West, the africans probably want to be a little careful about this one. Maybe make sure they maintain a few different links that are, if not controlled by the africans themselves, at least can be controlled by Brazilians, or Russians, or Chinese.
Russia and China? The US is more trustworthy than both of them, by a lot, and if there is one thing China is good at, it is extortion.
I mean, maybe you could find a few here or there, but for the most part, I'm guessing they'll have their guard up when they trade with us. They'll especially be on their guard with any american who struts into africa telling them, "How ya' doing buddy? We're way more 'trustworthy' than that other guy you want to do a deal with!"
It's not even just the same. The end result is way better than what a purely ideologically motivated organization would have been likely to achieve, if anything.
