It's quite ironic that Apple is setting a precedent for the intolerance of any symbol of slavery while they are knowingly supporting manufacturing which utilizes child labor, which is often forced labor. The epitome of hypocrisy which hopefully leads Apple to change.
I would absolutely agree that Apple's workers in China and elsewhere work under harsh conditions that would simply would not accept in the West.
But do you know for a fact that Apple utilises child labour or is that more speculation? I know it is common in clothing manufacturing (and other cloth-like accessories e.g. shoes, bags, etc) but didn't know it was common in electronics and or in China.
