No, they were cut off. Car manufacturers camp on ancient old nodes for 10 years at a time because redoing their own electronics design is expensive.  The second they canceled orders for the older nodes, fabs chucked the older, now-unprofitable machines due to no volume and replaced them with machines that DO turn a profit.
