This isn't a high horse, this is basic social behavior that should be the norm.  Exactly, you can do what you want when you want, right up to the point you violate someone else rights. Stealing their work because you think they have made enough off of it is ridiculous.  You can try to justify it all you want, but in the end you are wrong and immoral for thinking its ok to do.
