I don't think you're morally allowed to steal something you don't really need. You can steal bread if you or your family are hungry. You can't steal a game - come on you don't need it to survive.
In my humble personal opinion, though, stealing music to multibillionaire rock stars or films to multibillionaire actors isn't as unrighteous as stealing an application from a company which puts hard work of real people in it. Now throw me in jail.
