I think I agree, if that is legally possible.
I don't think apple provides any important infrastructure like Amazon, Microsoft and Google do.
It's basically a luxury company.
Might be bad for the people who already own iOS devices and need it to survive in one way or another (e.g. as a wallet).
Well apple could still operate the devices that they've sold, they just wouldn't be able to sell for a specified period of time, doubtful apple removes support anyways because then they customer trust.
