Seems quite possible that Sony just offered a lot of money to one of these script kiddies so that the authorities would be incentivised to do the corporation's dirty work.
The offer will never materialise.

Slashdot, where nerds forget The Law of Parsimony.
Perhaps some reading comprehension is in order. The OP didn't say they did it; they merely pointed out the possibility.
Oh well, in that case, let me point out the possibility that Elvis is still alive, that the Moon landings were a hoax filmed at a NASA's garage, that 9/11 was masterminded by the Rothschild family, the Chupacabra is related to the Yeti and Kim Kardashian, and "The Protocols of the Elders of Zion" is a real, historical document.
Hell, here is another possibility. Obama ordered the hacking and bomb threat because Benghazi. Or better yet, maybe Bush ordered Cheney to assemble a bunch of hackers back in 2007, but these hackers went rogue for lack of sex or whatever, beyond the original, official parameters of their mission, which did not include making fake bomb threats.
It is possible. You cannot prove it to me that this is not possible.
To borrow your own words, I am merely pointing out the possibility. Again, I cannot prove it (that the possibility is false), but I can say it (pointing it out.)
Anything that is not mathematically provable to be impossible is, by definition, possible. But just because something is possible, it does not make it reasonable. It certainly does not imply that such thing is even noteworthy of consideration.
Again, Law of Parsimony, or Occam's Razor or whatever you want to call it. If people want to spend brain cells in merely pointing out the possibility of really stupid, inane, batshit crazy conspiracy theories, whatever rocks their proverbial boats. They should not expect not to be called on it, though.
