I fail to see what the conspiracy theorizing is about.  Instead of having half a million infected PCs lose their internet connections back in March, the FBI arranged for temporary clean DNS servers to be put in place to allow affected users more time to disinfect their machines.  The FBI isn't attacking anything, just shutting down the TEMPORARY servers that were put in place 4 months ago.  Should they have shut things down 4 months ago?  Or should they have allowed the criminals to keep their botnet in place?  Speaking for myself, I'd rather lose my connection than have my internet communications hijacked by criminals.
