Yes, it needs an adjustment. It needs to be adjusted so that it actually works for black people.
What’s the assumption being made that’s the “worst”? Nobody is suggesting that manufacturers of this thing think slavery is a good idea. Nobody is suggesting that this was a deliberately engineered design feature. But just because systemic discrimination isn’t always the result of conscious decisions, that doesn’t mean it’s not systemic discrimination, and it doesn’t mean that it shouldn’t be called out when it appears.
This kind of stupidity happens all the time. @manybellsdown pointed out that it’s also water faucets, and video games. It’s face-tracking on your computer, it’s facial recognition software used by law enforcement. White engineering design and test this stuff on white people, and then it doesn’t work for POC.
It might not be deliberate, but that doesn’t make it acceptable, and it happens all the goddamn time. It’s not the devices that needs adjusting, it’s the awareness and implicit prejudices of the people designing them.
