You are thinking small and "old way".
The lesson is pillage *before* your burn. Not that the Vatican is a seat of knowledge. They just hold things they've taken from elsewhere.
In fact, in your example...the apple credentials are more like the safety deposit box itself (not the contents). The contents of a safety deposit box (like the physical Ipad) are indisputably property of the owner but the box itself is merely a storage vessel, which is subject to a contractual agreement with a third party. So I own the contents of my safety deposit box, but I don't get to break into the bank and empty it whenever I feel like.
I agree it wasn't a perfect analogy. But if you take the "box" as being owned by the bank. You are saying that the bank should open the box, dump the contents on a table, take the box away. In most cases, the person showing up with "rights" to the box assumes the contract on it. They get to keep the box under the same ToS as the previous owner.
Because one destruction of knowledge deserves another?
Aside from the spoils from conquered lands, what "knowledge" do you assert exists within the Vatican?
