It does not want ordinary users to disable this protection though. For instance, when libreoffice 3.6 was released, I installed it and it would not run because the code was not signed...
So I go to disable this protection and a dialog pops up that says something along the lines of this: "You can actually ctrl-click if you just want to run some application while this protection is enabled. Do you still want to disable it?"
I did not disable the protection, and it made some kind of entry in its database that says LO is allowed to run forever on this computer, and everything kept on working.
