2. No one who knows actual facts about this case has any interest in letting the truth be known.
3. We will never, ever know who hacked Sony, or why, until it IS in someone's interest for the truth to be known.

Within two years, no one is left on the staff who can still operate the "big iron" interface of the old "nail smashing devices" and now there's system-wide version lock-in. The boss bought in because of the blinky lights, reduced training time, highly-granular tracking, and the cost was only $15.00 more per unit than the manual version. He has already been promoted for his perspicacity. Capital equipment purchases nowadays tend to be for processes rather than actual equipment. I don't believe this is a great state of affairs, but I believe it's the true state of affairs, and people ignore it at the risk of their own irrelevance.
