Presumably no one said “let’s build the data center where the black people live, mwahahah.” Instead, they said, “let’s build the data center where it’s cheap.” Where it’s cheap also happens to be where the black people live, and that’s a pattern. The pattern has historical roots, but it also affects modern communities. The academic quoted in the article is likely highlighting this point, which probably to them seems obvious, given they are steeped in the field.
