Gutmann sites an example in his paper which can be found here that, "Windows Vista includes an extensive reworking of core OS elements in order to provide content protection for so-called "premium content", typically HD data from Blu-Ray and HD-DVD sources. Providing this protection incurs considerable costs in terms of system performance, system stability, technical support overhead, and hardware and software cost. These issues affect not only users of Vista but the entire PC industry, since the effects of the protection measures extend to cover all hardware and software that will ever come into contact with Vista, even if it's not used directly with Vista (for example hardware in a Macintosh computer or on a Linux server)".
Gutmann's final argument states that crafty hackers will find ways around Microsoft's security efforts just as easy as any other OS they've released and will ultimately end in doomed efforts, annoyed customers and more expensive, less functional operating systems.
