Apple was accused of racism because of the work of smart watches.

The Americans filed a class action lawsuit against Apple, suspecting the company of racism due to the incorrect operation of the pulse oximeter in smart watches. The initiator of the lawsuit alleges that the Apple Watch incorrectly determines the level of blood oxygen saturation in people with dark skin color. The fact is that the sensor of the pulse oximeter analyzes the color of the blood flowing along the user's wrist. It is possible that data is distorted upon contact with dark skin.
