No, they're just choosing where they decide sustainable such that it doesn't strictly require every body in the supply chain earning at least (ppp adjusted) poverty wages.

I don't mean this as like a nihilistic "buy anything because it's all awful" sort of thing it's just that we live in an inescapably mutual world so there is basically no direct line or direct chain from the base inputs to the consumer outputs and somewhere in that tree is a leaf that is terrible. We can choose the best that we can but there is no perfect and its a stretch to even claim there's a good.

this is the how capitalism kills us all. we cannot be ethical and so every day we betray our ethics until we begin to betray them as a matter of course instead of a matter of necessity.
