I think it's helpful to distinguish between "not whitewashing" (i.e., representing the actual demographics) and actively showing the demographics some wish the industry had (which is also what whitewashing is, although whitewashing only applies when the desired demographics are white). Your comment seems to appeal to "not whitewashing", but Apple here appears to be promoting its own desired demographics or else they would probably use characters who are either racially ambiguous (e.g., the yellow emojis) or else representative of the larger industry.

Of course, there's the possibility that I'm reading too much into Apple's intent based on this one sample. If we wanted to be more certain we would have to do a more robust analysis.
