I don't think of one minute any state actors were involved deliberately, the stakes would be too high, and for what?
Would still argue a catastrophic failure of some kind disabling some buses, could be that disabled the crew (hypoxic or otherwise), and some poor (clueless) bugger attempting to fly the a/c via the MCP, but ending up in the middle of nowhere.
As for all this leaked information, I suggest it is treated with some discrimination, a lot of it may simply be found later to be 'incorrect'.
I'm very much still with the theory this was accidental.
