There was no guarantee Intel would get the rest of the CHIPS money they were granted - even the Biden administration kept holding it back (after officially awarding it to them) - as there were doubts Intel could deliver.
I also wonder if some deal was made around 14A. Tan said he would not develop it without commitments from customers, because sales from Intel CPUs wouldn't justify the cost. This may be a way to ease that pressure and give Intel another chance even without serious customer commitment.
