I think you're ignoring the externalities of supporting a business/country that is doing things you don't agree with. If ACo can sell me widget cheaper than BCo because they dump the polluting manufacturing waste in a local river it's perfectly rational to decide not to deal with them. The intent is to make them change their behavior by impacting their business. Should we ignore the effects of our purchases just because we can get something cheaper or better?
