Digital Rights Management


Steve Jobs's main points on DRM

  • DRM has never and will never be perfect. Hackers will always find a method to break DRM.

  • DRM restrictions only hurt people using music legally. Illegal users aren't affected by DRM.

  • The restrictions of DRM encourage users to obtain unrestricted music which is usually only possible via illegal methods.

  • The vast majority of music is sold without DRM via CDs which has proven successful.
