I think the quibble may not be with the headline, which just says bias, but with the repeated use of "racial bias" in the article content. That is a somewhat loaded term in these times we are living in. A more neutral write-up might just have observed that the devices seem to have poor quality control and may not be particularly accurate for all skin colors. Caveat emptor and all that, but it is a $25 medical device.

"Pulse oximeters give less accurate results for people with darker skin" would have conveyed exactly the same information, but probably would have yielded fewer clicks
