The problem with this stance in regaurds to mining of minerals and other commodities, is that they are commodities. Apple not buying say coltan from an african conflict zone does very little to move the needle on price or demand for the products of said places, because commodies are fundamentally fungible. Unless every company/nation chooses to do the same, its like trying to divide up and keep track of water molecules in a cup, the reduced demand from apple is filled by firms that would have otherwise bought from the suppliers that apple is using instead.
