I'm not sure why you've been downvoted for this. Although I'm inclined to agree with their starting position it's hard to deny that quality investigative journalism shouldn't be about proving a preexisting hypothesis.
If you read the article, they already proved that Facebook was selling illegal housing ads that were biased racially and they proved that a common parole software was also biased racially. I think it stands to reason there are plenty of other inadvertent, or otherwise, issues out there.
The book "Weapons of Math Destruction" by Cathy O'Neill has plenty of other examples of how profiling algorithms often end up disadvantaging the disadvantaged.
