The same cannot be said for the poor Cobalt miners, so no they can't just will that info into existence simply because they "want to know"
And if the mine is in the midst of a warzone and you can't be sure if they aren't using prisoners or children? Then find a different goddamn mine.
Unless you have a way to prevent demand for these minerals, there is not a known, effective solution to these problems.
That's the hard part of supply chain vetting: trying to ensure that your contractor isn't trying to pull the wool over your eyes. If you think "a plane trip and a few days of a couple people's time" is going to be sufficient to actually ensure that you're getting responsible cobalt, well, I have a bridge for you.
No. Not at all. It takes more than that to vet suppliers in a place as developed as China. If you think that's all it takes in an ACTIVE WAR ZONE you're delusional.
I agree. Err on the side of caution. If it "can't be done", it'll be figured out soon enough when trade is completely cut off.
No. It took thousands of years of civilizational development to even create the state capacity to do this sort of regulation in the developed world. It doesn't just magically happen through some invisible hand nonsense. Governance requires concerted effort by a sovereign government. The only way it gets done is by forcing stability and creating a government, which is a responsibility I don't think you want to put in the hands of FAANG and Samsung.
Up until a few years ago, Cobalt was specifically called out as being a problematic resource, with incomplete audits and widespread violations. Now, Apple claims to have this under control. Either Apple is lying or misguided, or the initiators of the lawsuit are.
Frankly, I wouldn't be surprised if the initiators of the lawsuit were wrong. It seems that Apple often gets lumped in with other tech companies' labor and supply practices, regardless of whether their specific policies are actually more strict than common industry practice (cf Mike Daisey's "The Agony and the Ecstasy of Steve Jobs")
Disclaimer: I work for Apple, but don't shop for their Cobalt, so I have no firsthand knowledge of the actual situation.
