The RIAA filed 80 more lawsuits yesterday. And the SCO group has begun to infringe my copyrights on portions of the Linux kernel. In other news, I recently granted copyright for my original PPTP-linux client to the FSF, so they can prosecute other copyright infringement of my code. I also signed over my contributions to GNU Classpath and GNU libc. [The FSF's copyright assignment legalese is actually incredibly safe and friendly: they even allow you to reclaim your copyright if you eventually decide you'd rather resell the code or somesuch. Of course, the rights you've provided under the GPL persist, but it does allow you to go back and resell non-GPL'ed versions of the code if you like.]
I drafted a DMCA counternotice to MIT's Copyright Agent in response to Diebold's cease-and-desist letter. I'm getting it looked over by smart people right now =) and will post it when it is finalized. In the meantime, you may be interested in my advice on filing a DMCA counter-notice.
