That's all well and good for tools, but I haven't found any manufacturers of smartphones that aren't also sweatshops. Until that changes, I'm proudly going without one and letting the hypocrites know that. Then hopefully they'll feel enough shame so that they'll do one of two things:
1) Never complain about sweatshops ever again because they're complicit in it and don't want to be hypocrites. Then they'll go on to the afterlife and have to answer to whatever diety(ies) exist on why they just HAD to have that iPhone when they knew full well why it was so cheap. Then they'll hem, haw, and stutter because they've been had, and then the diety(ies) will shake their head(s) and kick them back down to earth for a do-over because their ethics were lacking and maybe, just maybe, they'll get it right the next time. While emotionally satisfying, this is not my optimal outcome.
2) Actually stop buying smartphones and other products made in exploitative conditions and demand that manufacturers clean up their act. Then they'll buck up and pay a higher price tag, and the workers will have a better life. Oh, the consumers will complain about the prices, and they'll resent the fact that they can't buy every shiny new gadget on the shelf now, but they'll have done the right thing in the end.
