It would have been factually accurate since it's skin color that's the issue.
Of course Arstechnica already knew that.
Look at the FDA documents linked in the article. The FDA says "The committee will discuss ongoing concerns that pulse oximeters may be less accurate in individuals with darker skin pigmentations."
It was never really about race, it was about skin color (the two are loosely associated), but Artechnica knows that "race" gets more clicks I assume.
I like to call these types of authors "racial carpetbaggers" - unscrupulous opportunists using race to further their own aims.
