What you actually want is to break the universe. It is physically impossible to revoke information unless it happens by a strange coincidence. 24x7, you emit information that races away with the speed of light. You can't chase it down. Physically. On the other hand, if you can decide which information stays, you essentially own the system. So, given the project's mission, I guess it is a requirement that information stays online as long as someone somewhere is willing to keep it.
