Re: couldn't agree more
The article mentions "Security researchers still have to abide by the Computer Fraud and Abuse Act."
And as you mention copyright law already existed.
So what is the point of the DMCA? Yes, I'm being rhetorical.. It;s for big businesses to have unfair control . It's so they can stifle competition, or embaresiing revelations they want kept secret.
It's wishy washy so that if it goes to trial, they can get their top lawyers to drag things out for years, which most people wouldn't be able to afford.
