If the sheer number of Apple devices at any given Occupy protest are any indication, it would seem the professional protestors who usually lead this kind of thing are going to bend over backwards to give Apple a free pass on just about anything. Christ, there were Occupy protestors CRYING the day Steve Jobs died--even as they rallied against our corporate overlords (with no sense of the irony at all). So unless you can sell them on the idea that Tim Cook has somehow corrupted their beloved Apple in the last few months, I would say your chances are pretty much nil.
And this isn't meant as flamebait. Seriously, go to an Occupy protest sometime and just look at the sheer number of Mac's, iPhones, and iPads you'll see. It's fucking creepy. They've been for shit at organizing on any other point, but they've apparently almost all agreed on at least *one* thing.
I am surprised that the Apple community does not go after Apple about wages like other did about the Nike plants outside the USA. Some recent article about Steve Jobs quoted an Apple executive saying paying US wages in mainland China (instead of $17/day) would only increase the price of an iPad by $70.
