The old "look, this is even worse!" fallacy.
Apple is a good target to pressure for better conditions. They have the money and the margin, they can afford to do it and could eat the relatively small cost. They also pride themselves on taking a moral stance on issues, like not unlocking phones for the FBI or a dead kid's parents, so working conditions should in theory matter to them. Of course, in practice, they care more when it doesn't cost anything to care.
The West has a big part to play in this. Sure, the Chinese do too, but it's often western companies demanding the lowest possible cost, and then moving to India if they can't get it from there. We can't shirk responsibility, especially when we have the power to do something about it at very little cost to ourselves.
