Good point
This
from a medium- to long-term perspective, this deal will inject the necessary capital into TMC so that it can work to become a rival to Samsung in terms of NAND Flash technology and production capacity."
seems to me exactly the reason that Apple has put up $3B in the Bain consortium.
This deal (lawsuits pending) would give Apple a source of chips and reduce their dependency on Samsung.
Similarly, the Apple investment in LG's OLED facility seems again to be done to reduce their business exposure/dependency to Samsung.
I'd expect us to still be talking about this deal in 2019 given the amount of legal stuff that needs to be dealt with.
