At the end of the day the internal practice of a company is your business in the way that you can choose to avoid buying their products. In my opinion steeping to their level by not being just is encouraging people to do that to all companies good or bad.
It sucks to realize your cunning plan depended on other people not reacting to your defections in ways you don't want them to, doesn't it? But the only effective response to realizing bad karma actually hurts is not to blame karma, or your victims, or even anyone who sees those victims and decides you're fair game, but to change your actions.
I'd say "welcome to real life", but like I pointed out before, even fairy tales do keep pointing this out.
