Apple's market cap is $2.7 trillion. How hard could it be for them to get a few nuclear-powered aircraft carriers and tell China, "We refuse to comply with your labeling requirements. Just try to stop us"?
Apple has about $40 billion cash on hand. A nuclear-powered aircraft carrier is about $10 billion, plus another 6 billion for the aircraft (taking a Nimitz class with 90 Super Hornets). Add in ammunition, crew, training, support craft, operational expenses. Buying more than one would seriously strain Apple's budget.
And all of that to expose it to China's anti-ship missiles and dare them to shoot. Seems like a terrible way to spend that money.
