Put it this way, if Tim Cook acted the other way as you wanted, he simply wouldn’t be CEO anymore; the board would have him promptly removed. You can’t head up a public company and leave that much money on the ground.
That settles it then: dystopian miasma it is! Can't let morality or ethics stand in the way of a small number of my dollars[1].
[1] Your 80% figure is totally bullshit. Only an idiot has 80% of his savings in Apple stock and Apple does not do 80% of its business in China. It has manufacturing elsewhere and so much cash that I'm sure it could quickly ramp up whatever production capacity it needs wherever it needs it.
Apple doesn’t care so much about making stuff in china as it does sells stuff. It is their second biggest market, quickly becoming its first, and is very profitable. Taking china out of Apple would remove probably 50%+ of its market cap, Cook would be put in an insane asylum by his board very quickly.
Again, ownership and stewardship of money isn't the highest good, and shouldn't be the compass that we use to guide all of our moral and ethical decisions (checked only by bare-minimum legal compliance).
Your logic is the same kind of reasoning that could easily be used to justify abusive sweatshops, child labor, and worse.
You also assume too much: some of this money is my own, though that's irrelevant. I'll be high and mighty about anyone's money if it's being used to prop up something unjust.
Of course we'll only find out if multiple people individually discover their backbones and forgo personal profit to take a moral stand, and I don't think that'll happen anytime soon.
