Africa has to have a chance to participate though. So, as unfortunate as it is, South Africa is within their right to participate.
The big issue is that FINA have largely ignored Africa. They are very lucky that Egypt, South Africa, Tunisia, and Algeria exist. Those are pretty much the only nations competing anywhere near world standards in various disciplines. I think we’ve seen some improvement in Africa, but Aquatics is by far one of the most underdeveloped sports in Africa. It may have a high amount of competitors, but those swimmers aren’t as competitive as the canoeists, rowers, sailors, fencers, runners, weightlifters, judokas, rugby athletes, and taekwondo athletes we’ve seen emerge from the continent recently.
