Affirmative action was banned across California and the article you cited itself says that the problem is only with UCs and not CSUs. The reasons proposed (distance, costs, number of UCs vs CSUs) intuitively ring true to me. Today's decision is obviously correct from a legal standpoint (equal protection clause bans all race-based discrimination) but the difference between CSUs and UCs actually suggests a positive path forward for helping boost Black and Latino enrollment in UCs- step one might be building a lot more and making them cheaper.
