I didn't read all the comments so someone else probably said this before me, the only controversy I knew about, I know there's more but I stopped paying attention to this when people started to get all testy... well anyway, it was over the names..

They originally had more 'white names' supposedly, basically the names children would have had in the time period they were setting it in. People bitched about it not sounding 'African enough' or something and the names got changed to what they are now.

I was just happy to have it be 2-D I didn't care what ethnic it was, of course I never even knew about racism till I moved up North and got called names because all my friends were Black back in Florida.
