They removed the link to "Digg-it" on their blog because:
"Until the Digg community shows as much fervor in attacking intellectual piracy as attacking the companies that are legitimately defending their property, well, we do not want to be promoting the site by using the "Digg It" feature."
Guess what, it isn't a crime to have people posting "infringing" decryption keys on website when the webowner AT LEAST tried to remove such content.
