Sony under siege by Anonymous

It's not like Sony had no protection at all. It's more like

"Don't break into my vault, get passed my armed guards, sneak through my laser system, and crack my safe"

"whered you get that tank?"

Same pomegranate.

And no one is to blame except Sony themselves for not having enough protection.
Look at it this way. No couple would want an unexpected child, but the probability is out there. What do? Neglect and QQ about it later?
If you do not want something to happen, you had better make damned sure it does not happen. End of story.
Sure, you may think the world is pink and balloons actually are round, but someone out there is pretty keen on fucking your life up just for lulz.
