The reason for removing the package from the repository was not that somebody realized that the files can be copied. We know pirating Angry Birds needs pretty much no effort at all but we still made a deliberate choice to go forward with this game on N900 nevertheless. Personally I would just like to believe that the community has enough honest people who realizes that by saving the few dollars on a game you like you very effectively doom the platform from getting more professionally made games. But there's still some threshold how easy piracy can be and having to write only three words to the terminal clearly exceeds it. That's why the package was removed.
