Intel currently doesn't have enough capacity to make their own chips and are rumored to be outsourcing to Global Foundries as a result ( https://wccftech.com/rumor-intel-moving-select-cpus-to-globa... - huge grain of salt on this one ofc, but the supply constraints on Intel's fabs are well known - they mentioned it even at their earnings call) - why would they stop making their own products to make Apple's instead? Apple'd have to pay an absurd amount for that to make sense.
