>leaving flaming bags of dog poop on your front porch before ringing your doorbell and making a getaway by segway while cackling madly. yet, every day, i resist the overriding temptation

If there were millions of dollars to be made in the flaming dog shit Segway getaway business, I am positive many would succumb to the temptation.

So your comparison is unfair, it's easy for you to avoid such a behavior because you have no benefits. Not securing a device is a significant economic win for the manufacturer, as explained by the thread originator. You get a device that "just works" as opposed to one with complex key setup instructions that by necessity must default in the misconfigured state (else, you bet everybody is using the defaults).
