Let me sum up what I know and have learned about Stefan, you may not care, but I'll say it for the rest to read.
He's a self proclaimed free market anarcist or anarcho capitalist, most if not all people who ID with this position oppose copyright, not just the government enforcement, but the entire concept that ideas or information can be protected or one can use force to stop another from spreading it. (I should add, another prominent speaker on this topic is Stephen Kinsella who has at least reposted an article agreeing with Walter Block that blackmail should be legal)
Anyway, the issue at hand is a person who doesn't believe in either using government to get things done, or the enforcement of copyright, has actually used a government law as a threat to force a company to remove information, which he has admitted has nothing to do with copyright. At the very least, it's abusing a law for an ulterior purpose, aside from legal trouble, he's a hypocrite for using a law he doesn't believe in.
