Well, Occam's razor comes through again. :)
Here's the list of probability of how and why things occur as they do.
RevDisk's Razor of Causation:
1. Bad %#)#&#@ luck
2. Incompetence
3. Something incredibly simple and/or stupid
4. Something incredibly petty
5. It was actually planned ahead of time in an organized, coherent manner for some mundane purpose.
6. Every other possible or logical conclusion
7. It is a conspiracy or dark sinister purpose
