Having said that good or bad, right or wrong concepts are somewhat questionable for the art because those are subjected to time, the costumes and the collective judgments, I have no problems in using a font or the other. There's no way to say that a font shouldn't be used, simply because it's just matter of personal opinion.
In any case this has not to be a tragic map. As you can see there's no SOS Africa logo on the map, this because this is not the SOS Africa map but the reward map for a charity event.
Now using a bit imagination, let me make an example, if I was a very rich man and I would be able to ask to someone to build a car for a Africa charity event, to give away with a sort of auction, I wouldn't ask to someone to create a car that makes people sad. Who will drive a car that make sad! Probably the car can be customized a bit or painted with some african colors, but I can't ask to paint the image of a poor child suffering on a car door just because the car was done for a charity event to raise funds for people who is suffering.
Back on our map, our task isn't and wasn't to give to everyone a map to remember all time about the sufference in the african continent, but more just a new africa themed map as reward for a good cause.
So for the font use one or the other is the same for me, up to the community to decide...as said imo it's just matter of common taste.
For the elephants, I'll turn them.
