Relatedly there's a Map Men video on why north is up. [0] I don't buy the whole top is 'good' and lower is 'bad'. I think the bias is just a lot of the groups that made maps were located north(ish) and traveling roughly southward which made it a convenient orientation, especially during the age of sail.

The discomfort visible in many commenter's reactions is telling, even if it isn't a good vs bad dichotomy.

The fact of the matter is that any data visualization brings with it some advantages and drawbacks. This can be projection, orientation or centering related. Acknowledging these drawbacks can be useful, and so is trying out alternative representations of the data every so often.

One thing I think can be acknowledged is that the poor job traditional maps do of representing Africa has affected policy towards countries in the continent for the worse. For instance misguided infrastructure projects.

And looking at the map, it would be hard for those map makers not to be north(ish) since the South is mostly ocean. Not too many civilizations that have sprung up in the ocean.
