Google develops Android which runs on many devices made in similar or worse conditions. They could change the license under which Android is distributed under to include a clause that it cannot be used on devices that aren't made under certain minimum labour standards. They don't. Are they evil too then? It's really a lot more complex than good vs. evil. There are many fine religious books that tackle that subject. This is an economic issue not a religious issue.
You are really suggesting that a company create an open-source OS that is supposed to run only on devices produced under certain labour standards? OK, so if you put some software on Github and a company use it on any computer manufactured in China you are evil? This is the same principle that the iranian government is using on the Saeed Malekpour case and it is absurd.
Not really just taking the argument to its logical moronic extreme. Google could simply change a few lines of text in a license agreement and (somehow) make life better for people in China. It's no different than the people who say Apple should (effectively) abandon the Chinese labour market and somehow the Chinese people would be better off.
