(a) Have DRM systems gone too far, as some critics claim? Recall the 2005 Sony BMG copy protection case involving the controversial “rootkit” problem (examined in Scenario 9-2).

(c) Do companies like Sony need strong DRM systems to ensure the protection of their intellectual property rights?
(d) What kind of compromise position might be reached between users and content owners in the ongoing debate about DRM systems?
