"Western" seems like an odd term to distinguish Europe/North America from Africa, but I assume that's what you meant.
I don't have any data to back up or refute such a claim, but it makes sense: Europe & North America have economies of scale for internet infrastructure, including hosting, so hosting there is presumably cheaper than in SA or other African countries. Which drives the domestic demand for hosting abroad, causing that money to not be reinvested in the local infrastructure. I don't know what the solution to that is. Maybe global CDNs building (more) datacentres in Africa will bring some of that money back and have a positive impact on the local ecosystem? (Taking their hosting money abroad is presumably the rational choice for most African companies, so it's difficult to fault them for not "helping themselves")
