If I owned a bunch of vending machines, and someone came to me and said "Hey, I found out that if you put a credit card in the dollar bill slot, it gives out free soda and empties all its coins through the return slot," I would a.) be pleased to have been informed and b.) not be upset that they did this. If a neighbor came to me and said, "Hey, your mailbox that's located at the end of your long dirt driveway is protected by a wafer lock that can be opened by simply slapping the side of the mailbox in a funny way," I would maybe wonder why they were slapping my mailbox but I would be grateful that they told me and I would want them to continue doing whatever weird shit they were doing (so long as it wasn't causing damage). When you put property in a public (or practically public) space, there's an expectation that it will not be treated as though it is on private property. There's a big difference between someone jiggling the door to your home (where you physically reside) and jiggling the lock on a mall gumball machine or the handle on a commercial fire exit.
