Little effort is needed to provoke outrage about racial discrimination, I think that it's up to good citizens, particularly journalists or those with a 'loud voice' to make sure that they don't stir the pot and create unneeded tensions and hatred for no good reason other than more clicks.
It would take a lot to make me believe that the wording wasn't purposeful.
When I was growing up, I was one of the few white kids in my circle of friends. One of the kids was always beating his chest on how the white man is keeping the brown man down. This is exactly the type of nonsense he would bring up.
The pulse oximeter wasn't purposely designed to give false readings to darker people.
I see a bias. However, maybe the testing was done only on poor white people because that's what the testing company employed (due to operating in a poor country with no significant "coloured" people population). Everybody wants to save money. Test results almost do not matter if the test is "done". Especially when "best practice" comes from SW.
