The truth is twofold.
One: if the barrier can be melted according to magic rules, then it is no real barrier. It is a sweet candy coating that melts in your mouth, not in your hands.
Two: if a corporation is made of many incidental strangers who happen to share an employer for overlapping moments in time, and the system has at least one authorization bypass, then so does the audit trail.
If you don't think corporations implode, suffer from disgruntled criminal employees, sell out to rivals, go completely bankrupt, or land themselves in jail, then bet all of your secrets on the idea that what they tell you is 100% truth.
