I realize if I kept tabs on all large corporation's ethics, in all likelihood I would find myself unable to purchase anything from someone respectable. That being said, despite becoming a large company being synonymous with it losing it's innocence, it doesn't mean that they all have to become porn stars.
Anyone who thinks my opinion is cheery picked or hyperbole doesn't follow the sweatshop labor, environmental destruction, discrimination against customers, etc in Apple's last few years alone. Using other unethical companies (none of whom were tech might I add) to justify their atrocious actions is borderline retarded. We might as well just let murders off the hook because those serial killers are so much worse in comparison, right?
As a consumer, all I'm trying to do is support companies that act the best, even if that means picking whomever is the least undesirable.
