This is a very insightful comment and you've hit the nail on the head throughout.
Everything we have learned about Harry since Megxit (his paranoia, crippling jealousy of his brother and sense of victimhood) strongly suggests to me that Harry's 'love of Africa' was always mostly love of travelling and being treated like a god by those he met - classic white saviourism. I have no doubt he also wanted to do good and saw it as 'his continent' where he could make a difference but mostly get support and adoration in a place with which William was not associated.
The clue is in the oft-used phrase (oft used by the media because it was fed them by the Palace): 'Harry's love of Africa'. Africa is a vast continent with many different countries which really have little in common with each other culturally, economically, religiously or geographically. Plus, it's still heavily tribal, with lots of tribal conflict. It's not an undifferentiated, amorphous hugbox for a publicity hungry prince.
Before Megxit I think the British in general were willing to overlook this because we were bought into the Palace created myth of Harry the big hearted cheeky chappy. But since 2020, the conversation about 'Africa' has changed a lot. Self-determination is the buzzword; not passively accepting help. Plus, tbh, China is pumping so much money into African countries' infrastructure and industry - the leading countries of the continent are increasingly facing east, not west.
If you run Malawi, say, which would you rather: Europeans bringing handouts and urging you to do subsistence farming (a miserable existence) in an ecologically sustainable way because CLIMATE CHANGE - or a Chinese PE firm offering you $billions to build a few massive fuck off mines and factories and make your people rich?
Yeah. Not a contest really. Malawi, and many other countries, have made their choice and they've chosen Beijing, not London or Paris. Harry's caught on the horns of a huge shift in the orientation of the countries of Africa. He's not dealing with it well, and I have no doubt that any investigation the Charity Comm does will also eventually show some funny business with diversion of funds to the H&M's own public reputation burnishing.
