Unethical companies are doing a similar thing with temporary foreign workers in Canada. I want an app with an ethical rating system for companies so I can research easily and buy from companies that aren't jerks. Something based on environmental stewardship, treatment of employees, customer support, etc. As for Amazon, this article made me resolve not to use them, but I'd prefer not to wait until a story blows up to be informed enough to be an ethical consumer.
