This is absurd...
Is it? Apple got a FDA certification for the ECG, if that isn't for all consumers it's a problem. On another note, the FDA handing out "certification" in addition to "approval" seems like a deliberate way to confuse consumers when one is basically a stamp for money.
Isn't this a bigger problem involving all pulse oximeters? It was at least two years ago that I first heard that the darker you are, the more likely you will get a false high reading on one.

Do you feel they should have a disclaimer about it being harder to take picture of dark skinned people in many settings with their cameras as well? Did you actually read the ToS or EULA?
There are slightly different rules for health devices than for leisure ones. If the problem is real, then it seems reasonable to me for Apple (and everyone else, just to be clear) to be made to amend their printed materials to properly disclose well-known-to-Apple problems with oximetry in darker skin. Again, if the problem is real, then they guy deserves a refund, fees covered, maybe a small token for the effort, an…
What claim did they make? AFAIK, their page on the oximeter always had a disclaimer (the current one says “Blood Oxygen app measurements are not intended for medical use, including self-diagnosis or consultation with a doctor, and are only designed for general fitness and wellness purposes”)

Is "health device" to medical device as homeopathy is to actual medicine?
Maybe we can require people take selfies in sunlight with a known camera sensor and white balance and exposure to accurately gauge their natural skin color, then have a corrective calibration factor sent to the watch's oximeter.
For an imaging sensor, the sensors are designed to be sensitive at different wavelengths and in different dynamic ranges, with some historical set points determined by major manufacturers being located in Japan. While darker tones do imply less collected light, this seems like a very solvable problem with in-camera image processing.
Another interesting question is around non-invasive neural sensors. Many EEG electrodes work relatively poorly in thick or curly hair, and there's been several efforts to develop EEG electrodes appropriate for natural hair [0]
