It's not bad behavior. The companies that profit off this try to make you think it's bad behavior because they don't want to risk your taking any profit away, and they've installed laws that let them get away with this. They can violate to their heart's content, but unless someone else in the oligopoly sues over the matter (which they would never do, because the precedent may prevent their abuse of the law), the peons will be forced to comply. That's not how a competitive marketplace works, and it's why we have such a hard time breaking gridlock on web properties.
