The Zoom example is a racist algorithm. It was built using a against a data set that produced different results for different skin colours. The Twitter example was not a racist algorithm. It would consistently pick one head over the other, but it had nothing to do with the skin colour. It might preference the black head for some pairs, and the white head for other pairs. In the second example people anthropomorphised the algorithm. They assumed that any example of a preference for an images was due to a racial bias. It was easy to keep feeding it images to get to an input that confirmed this assumption.
