I'm surprised it took until very recently for Apple to start spinning-up alternative supply arrangements and manufacturing in other countries - I guess they expected that the PRC would improve their human-rights situation by now.
Is that something China could realistically do without irreparably harming themselves in the process though? It’s not just Apple’s supply chain that goes through China, it’s everybody’s. And once China demonstrates they are willing to do that, everybody is going to see a China-based supply chain as a gigantic business risk and look elsewhere. Apple can weather that kind of setback, but it would be an existential threat for most businesses and they would need to be proactive. Apple would go elsewhere and lay down the infrastructure, then everybody else would follow in their footsteps.
As far as I can see, China can throw their weight around to a certain extent but their hands are tied when it comes to stronger action because "Apple’s PR saying the wrong thing" is nowhere near as harmful to them as companies diversifying their supply chains en masse.
Think of Google then. Google's exit from China achieves one thing, that is becoming irrelevant to the Chinese people, while giving its competitor a free run of the world biggest internet market.
Control through market is a trick that US has been playing since WWII. It is proven to be effective.
Not being complicit in genocide isn't enough reward by itself?
Interesting how Microsoft's President called for a Hippocratic oath for engineers, while dodging the real problem - decisions which have real impact are made by executives keen on maximizing bonuses.
