Of course not. But that doesn't excuse misrepresentations of what it did. Or what could happen to anyone who removed it.
In the list of replies to the Sysinternals blog post on the Sony BMG rootkit, there are folks who claim that both discovering as well as removing the rootkit are DMCA violations. One claims that this was clearly stated by a management figure within Sony BMG, and there is a name. I can provide a linky if you must see it. You can decide...well, you've probably made up your mind as to the credibility of such a source to begin with.
It's a matter of circumventing copy protection. Looking for & detecting the rootkit, let alone removing it, is exactly that.
That's a violation of the DMCA as I understand it. You understand differently? Show me the section of the DMCA that says it's okay to circumvent copy protection, and I'll give ya a Twinkie.
And the fact it let you copy does not excuse the fact your backing a law that would make the detection and removal of this root kit illegal and punishable by prison time..
