btw I agree with fuji on the question of ethics here, but do feel that there is a form of "duty" to the CC company. When you signed for the card you accepted the responsibility of paying back the monies the CC company paid out on your behalf.
Let's split some hairs (ethics debates are so much fun that way).
The argument that you don't owe a duty to a corporation is essentially that the corporation doesn't feel it owes any duty to you. A corporation, generally, considers only the interests of its shareholders. Unless you're one of them it won't consider your interests at all when making its decisions. Since it isn't considering your interests, why on earth would you consider the interests of the corporation when making your own decisions?
On the other hand, when it comes to the laws of the land, we're talking about a social contract with one another via the government. Arguably you DO have a duty to obey the law not because of the corporation but because that's what you've agreed to with the rest of us, and, unlike a corporation, society as a whole often DOES consider your interests when passing laws--setting up things like welfare, bankruptcy protection, subsidized education, healthcare, and justice systems that benefit you as much as anyone else.
If you can screw a corporation over without any other harm to your fellow citizens, without undermining the rule of law, etc., then more power to you--bend them over the counter and screw away. Rest assured that if a corporation can screw you for profit without breaking the law (or sometimes just without getting caught breaking the law), it absolutely will bend you over and fuck you as hard as it can in the name of increasing shareholder value.
(A caveat to that is often there are stakeholders, like co-workers and friends or other members of your community, who have an interest in the wellbeing of the corporation, and it is sometimes necessary to consider their interests--if you're going to screw the corporation so hard that they're out of a job perhaps you've gone too far because you've harmed their interests.)
