Some corporations are shamed into doing the right thing, typically after an extensive period of morality-free cash-hoarding. Apple was just fine with their supply chain until news emerged of conditions down there (and Cook being a logistic guy, he’s clearly always known), at which point they hd to save face. Similarly, they keep saying they are green but have no qualms pushing out billions of unrecycleable and un-serviceable electronics every year, without taking any real responsibility for disposing of them.

Corporate ethics are hypocrisy all the way down.
