Additionally, I don't know of any other major system that has gone 4 years without an open-source hack. Since 2008, the only BD+ rippers are commercial.
Also, credit should be due to the designers of Cinavia as it has succeeded with the least secure design possible. It's a watermark in the compressed stream that is checked by the _player_, which mutes the audio if it is present. All you have to do is patch the player to ignore the mark or play it with VLC and it is "bypassed".
However, even the commercial rippers have not yet stripped off this watermark and all bypasses other than playing in VLC have been partial (e.g., needed an old PS3 firmware).
