"Attempts to gag the blogosphere from publishing details of a
DVD crack have led to a user revolt. The fight centered on a
'cease and desist' letter sent by the body that oversees the
digital rights management technology on high-definition
DVDs. It requested that blogs and websites removed details
of a software key that breaks the encryption on HD-DVDs.
The removal of the information from community news website
Digg was a step too far for its fans. As quickly as stories
relating to the issue were removed, they were re-submitted
in their thousands, in an act described by one user as a
"21st century revolt".
