Clear Key was introduced as a red herring to "prove" that open CDMs are
possible. That is also the reason for the contradictory statements made
by proponents of EME regarding Clear Key.

This is not only about Open Source browsers. EME first of all is an
attack on Open Source operating systems (especially Linux distributions).

EME is a Trojan Horse which would enable privacy violations. One of the
supporters of EME (Google) promotes or promoted such technologies.

Below I have appended a quote from March 2012 from Widevine ("a Google
Company") regarding "silent monitoring".

That is one of the reasons why it is a shame that the W3C is involved in
helping to create a Trojan Horse enabling evil things like this.


"Here's How It Works:
Content is encrypted, stored and distributed to the user who then
watches it in a browser or video player. During playback, encrypted
content has been decrypted and the video is now vulnerable to piracy
simply by downloading a free software tools such as screen scrapers and
stream recorders which can pirate the video stream to a DRM-free file.

In the background, Widevine’s digital copy protection solution monitors
for the acceptable usage of content. If a user attempts to use a screen
scraper or other piracy method, Digital Copy Protection will detect this
and produce a number of customizable responses from silent monitoring to
revocation of viewing rights."
