I think it's obvious why fingers immediately point to Apple vs other manufacturers. It's because they are the most profitable. Boast about how profitable they are. Boast about how much they do for the working conditions, etc.
Apple hasn't been the "underdog" for a very long time and some people still think of them that way and are surprised when Apple is attacked for doing just what everyone else does.
Apple isn't necc. MORE accountable. But they are accountable (I'm not referring to this specific incident, mind you - just in the logic in finger pointing). And if they enjoy being "#1" in the industry (perceived or not) they will always be in the headline when the S!@#$ hits the fan.
