TSMC may not have needed it but Apple did invest (pre-order) and they will continue to do so. There is not exclusivity but pre-purchased capacity and similar video games and kickstarters. They don't always work out for Apple (the Sapphire glass) but majority of the time they are working out perfectly (iPod Toshiba Hard Drives and the TSMC M1 cpus).
