It is not so trivial. The belief is that there are some mystical data. They possibly require some management, but that's a different story. Now, the management is off. Where are the data?
What happens with the Moon when nobody looks at it? An urban legend tells that Einstein asked Bohr if he really believed that it would disappear. Bohr answered: show me an experiment, which would prove otherwise.
OO [behavioral] interpretation is that there is no data behind the management of. Once management is off, so the data.
