>But we apparently agree that "somehow found a way to describe this as an unfair advantage for White students" is actually accurate on their part?

I agree that Whites also got an unfair advantage over Asians in college admissions, yes (I haven't kept up with the state of things since some recentish supreme court decisions so I don't know if this is actually still the case).

>Then we shouldn't use it as such.

It isn't used as such. It's used to measure a student's current aptitude in math and English, hence the discontinuation of its use in California leading to the poor math outcomes for students described in the article this entire thread is about.
