Part of the problem is the over-reliance on metaphor. They're flawed, and often confuse people. The suggestion of people walking into houses, or sticking their hands through open windows (or even just peering through them), tends to unsettle people. It brings to mind trespassing and countless episodes of Law & Order that start off with rape and murder. So why are we willingly choosing to discuss encryption, networking, and security research/disclosure through analogies that set people on edge from the very beginning? We lose the listener immediately. And probably poison the well, too.
