All those fun face filters had trouble with black people too and probably still do. It wouldn't surprise me if tech lord programmers literally never had black people in their training data for whatever machine learning actually does these algorithms.
So I know some people who worked closely on this stuff at Snapchat and what not, including a couple of black guys, and the reason for some of this stuff has a lot more to do with cameras and broader shadowing type stuff than anything training data related.
This said, the fact that cameras tend to not work as well for darker skin tones is definitely a real problem that needs to be worked on.
