People get too precious about open source details
To be fair it's probably just a clash of cultures.
Having done Air Defence(A.D.) a million years ago I just about remember our procedures being placed in some sort of security wrapper. It came as something of a shock on transition to the civvie world to find of those same A.D. procedures being "open source", contained in the likes of books, checklists and Flying Manuals ....and if you think about it logically many of the procedures have to be "open source".
