So the story is that a state level actor who is pissed at a company over a particular bit of video, steals a load of data and then does not check the stolen data for the video they are pissed about before publicly releasing it online themselves, while simultaneously demanding that it isn't released in any format ever?

I'm not saying that this isn't what has happened, as governments are capable of wonderfully insane levels of stupidity at times, but it does seem relatively unlikely.

This more looks like someone who is massively pissed with Sony, not a particular film, and is just running with the NK angle for comedy chaos-monkey reasons.
