You're conflating copyright infringement and DRM circumvention. All of the safe harbor provisions and takedown measures have to do with hosting copyright infringing material. They make no mention of needing to do anything if you're hosting DRM circumvention technology. By your logic, I could submit DMCA takedowns over libel and the service provider would have to take it down despite it being obvious that libel is not part of the safe harbor provisions.
