Why not? See Gutmann, Peter: "A Cost Analysis of Windows Content Protection": http://www.cs.auckland.ac.nz/~pgut001/pubs/vista_cost.html http://www.cs.auckland.ac.nz/~pgut001/pubs/vista_cost.html 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 before Vista was released, this guy predicted that third-party hardware would exhibit persistent stability problems with Vista. And, lo, the reports from the field just keep coming in, even years later. (Though presumably the bugs have gradually been worked out by this point.) (Note that I can't report any bad Vista experiences myself; I have not used it.)
