Thanks, I updated the text putting the US bit in parentheses.

For black-list/white-list replacing with block-list/allow-list (also more descriptive) is a a clearer example of the rationale to change the terminology. In general it is about the whole range of feelings and perceptions around "dark" and how they lead to biases in people, often without being aware. If we become conditioned that uses of "dark" invoke gut feelings of sneaky, shady, illegal, secretive, nefarious, evil, etc. some of that may seep through in how people with dark skin are considered. Whether that is true or not, in any case, the alternative terminology being more descriptive, it is low-hanging fruit to adopt it.

I agree that "dark pattern" does not to me think of race, either, but I think that "deceptive design" is a better word anyways.

It is not really about what it directly means. It is about changing the social ideas of white or lighter things meaning good, while black or darker things meaning bad.
