What do you imagine HDCP and CI+/HD+ was created for?!
Imagine a scientist discovers hidden risks of a technology. A TV station broadcasts the report in TV news and people record it on their great new BluRay recorders. Afterwards a mighty company, military or whatever malicious power forces the TV station to "unbroadcast" these news by blacklisting its file ID through HD+. Now e.g. an NGO wants to clear up about the risk by showing the recording of said tv report to the public or start a lawsuit or public protest - he inserts the disc, but the screen stays black and the recorder immediately deletes the video file from the BD and internal harddrives to destroy all proves of existence. This is the mindedness DRM was genuinely designed by!
HDCP also includes fully automated firmware upgrades. Thus any BluRay manufacturer, hacker or evilminded government may easily destroy your entire HDCP capable hardware by sending through TV broadcast a malicious update that contains invalid decryption keys and blacklists all legal update sources. Because the stuff is fully "security by obscurity" and overwrites the flash rom in any connected HDCP capable hardware, it is the perfect method to destroy a nation's communication infra-structure once all people have upgraded their hardware to the allegedly so great and modern HDTV stuff.
