I'm not sure how useful analogies are in this case, even so I get pretty upset over a lot of popular poor quality business books (and similar) that have real impact on things. If you want to make a comparison you can equate things to hardware where things like quality control and yield is instrumental. If you buy a plastic case that after a year self-disintegrates because while it looked the same it wasn't manufactured to spec. When this could potentially happen to every part of your device this quickly becomes annoying. Yet, this is how software is all the time and is further worsened by a lack of due diligence and quality control. How many developers can get the time to properly verify a technology or library. Not to speak of if it's even fair to expect developers to be able to reach those conclusions.
