As much as I hate those little turds too, they fill an interesting niche: If the little turds didn't write their mild-annoyance malware, then we'd only discover the security holes in our software long after the seriously dangerous folk (spies, thieves, superpowers) had already compromised our systems, stealing our money and our secrets.

Not that that sort of thing doesn't already happen anyway, it's just nice to know that most of our front line security battles are being fought over malware that's merely an annoyance as opposed to something truly frightening.
