Privacy manager should all present options to completely stop loggins from applications

I read about the Privacy manager in this blog post here https://www.eff.org/deeplinks/2012/03/ubuntu-1204-will-bring-os-level-privacy-options. And the points that they state are valid.

Like for instance, if you blacklist firefox, it stops Unity from detecting whether the user has run firefox or not and perhaps does not show it in the recently used apps. But this does not stop firefox from logging the web history of the user. The privacy manager should atleast display a message saying that "Privacy manager does not stop the application itself from logging data" but just Unity or Zeitgeist since otherwise the user will be confused. Or, you should provide options for the privacy manager to disable the logging of the application itself i.e stop firefox from logging web history.
