this is 100% true and I'm glad someone is writing about it, but also a lot of the writing around it calls it "redlining", and at this point I suspect that messaging makes it sound like it:
a) is merely a historical accident resulting from the original sin 90 years ago of people choosing consciously to be racist;
b) is not an emergent property of a mode of production that provides vital services preferentially to the people who are most able to pay for them;
c) can and should be remedied by rewarding ISPs with further government subsidies to "extend service to underserved communities" instead of making internet access a public utility with a universal service mandate
