I don't think that's a valid argument. It's perfectly okay to notice that what you're benefiting from is not something you want to support. I can replace words in your argument thus: "It's amazing how many people have jumped on the safe work conditions bandwagon when they have reaped the benefits of horrible work conditions in third world countries."
Are you referring to GMO crops and safe working conditions as the apples and oranges? Rest assured that I am not comparing them, I am simply reshaping your statement to support my statement that "It's perfectly okay to notice that what you're benefiting from is not something you want to support."
