This is probably the core of the conflict there - there are researchers that aim to remove technical bias from technical systems and expect to stop there, not going into social issues of how the systems will be applied, as they consider that (e.g. solving the biases in the society) as a separate issue.

Dr. Gebru, among others, expects and insists that they do go beyond that and try to get involved in the social consequences of tech. They refuse, ergo conflict.
