Rebecca Jeschke has a brief article on Electronic Frontier Foundation offering modest support to the way that Section 512 of the Digital Millennium Copyright Act works – that is, the Safe Harbor.
EFF also mentions Section 1201, which apparently makes it illegal even to publicly discuss materials covered by DRM, or digital rights management, under the DMCA. The case is Green v. US Department of Justice. There is more info about the case here.
It seems scary that it could be illegal to "discuss" or report something. But the original Communications Decency Act tried to do that with some aspects of abortion back in 1996.
