What will they use instead? SAT scores do a good job of predicting success in college.
In practice: things that satisfy ideological goals and maximize fundraising outlook for the institution.
That said, there's a confounder here: schools which remove SATs as an admissions metric are schools that are looking for different things than academic preparedness/quality. It's likely that they're using methods and rubrics to deemphasize the predictive quality of GPAs as well.
GPA is fairly objective (though less so than the SAT) and predictive (more so than the SAT) as a standard. Accounting for the courses taken and the high schools the courses are taught at, you could select a class purely based on grades that is highly qualified and prepared (and incidentally would also have high SAT scores; GPA and SAT are correlated). But a university removing the SAT from admissions is also likely to be trying deemphasize the component of GPA that's predictive of quality as well.
My point is more that universities can (and do!) create a different representation of coursework performance that accounts for rigor. But a university that eliminates the SAT is also likely intentionally making that representation less predictive of undergraduate performance to allow weighing of things more than preparedness/quality as indicated by grades.
What makes SATs so important is that you get a very limited preparedness signal from kids with 4.0 at the crappy school; combining test scores with GPA allows for a selective school to get a much more meaningful signal for quality/preparedness.
My motivation here is to push back against the scores alone are enough idea, though it's an understandable reaction to the people who by all appearances think quality/academic preparedness should be a secondary concern in admissions.
This seems natural to me, as GPA seems inherently less objective (different schools, different teachers).
I think it's fairly strange that universities are getting rid of using them. One explanation is that it helps protect them from lawsuits like those against Harvard, as there is less incriminating evidence. I fail to see how it actually helps students.
These are just selection for middle-classness.
There are many White and Asian people who tick the Hispanic box, thanks to Hispanic-sounding names... Often at the suggestion of their high school counselor.

This is kind of a nitpick but the SFFA case doesn't try to argue that there are racial quotas, instead, they argue that whites, specifically, are admitted where Asians should be. This, despite whites being the only race that is accepted disproportionately less relative to their general population percentage.
SFFA doesn't attempt to say anything about other racial categories but that Harvard has designed backdoors to admit whites at the expense of Asians. The case may not have any impact on racial quotas or affirmative action if it wins. If it wins, there will just be fewer white people admitted I assume.
