Even so, the algorithm does give insight how the scheme works. A "revealing" bug in their software that leads to the format being cracked (the way DVD Jon managed to crack CSS because of a bug in a third-party video player) might make them liable for damages. The major stakeholders in their DRM are not Sony themselves, but the publishers.
