Why do you take this as fact?
"Emerged in South Africa" is likely correct: the first probable case was identified in Pretoria, SA on 2021-11-04, and the first confirmed/sequenced samples were also from SA and Botswana that same week. There weren't any confirmed cases outside of SA until 2021-11-24, so I think "originated in South Africa" is pretty likely.
Sure but how many other African states were doing any sequencing? Or even any substantial testing? It’s quite possible that the variant was evolving in Africa for a long while until it was discovered in South Africa. Also if you were a super duper shady institution releasing modified viruses into the wild you would probably not release in your own country and not even somewhere it can be detected quickly. So black Africa is a perfect candidate
