That article WAS true but in 2015, the UC regents voted to eliminate most of the financial aid given to out of state applicants.
The issue has always been that the UC system is funded by California taxpayers so in-state applicants should reap the benefits. The UC regents have also voted to cap the # of OOS students admitted to the UC’s at around 20%, so it will be even harder to get an acceptance as an OOS along with no FA.
