The FCC rule mentions several attributes, race being only one:

> The rules define “digital discrimination of access” as “Policies or practices, not justified by genuine issues of technical or economic feasibility, that (1) differentially impact consumers’ access to broadband internet access service based on their income level, race, ethnicity, color, religion or national origin, or (2) are intended to have such differential impact.” As the law requires, the FCC will consider arguments that legitimate business impediments preclude equal access to broadband service in particular communities.

I doubt people would have the same reaction if they realized it was primarily about income and not race. But everyone loves to talk about race.
