I can give you a real answer, because I asked my wife this exact question (she’s black and uses the skin tone closest to hers, I’m white and also just use yellow ones). She said it’s so rare to get to choose a digital representation that matches her skin tone that she just thinks it’s fun to get to do it for once.
I think it is a bit of an unclear wording personally. “Made with”, despite technically meaning what you’re saying, is often colloquially used to mean “fully created by”. I don’t mind the AI tag, but I do see the photographers point about it implying wholesale generation instead of touchups.
