One of the glaring problems with most of the mechanical failure theories resulting in a decompression is that - if they had enough control to turn around and head back towards Malaysia, why in the world didn't they initiate a descent? That's
the number one thing you're taught to do in the event of a decompression after putting on your oxygen masks.
Of course, accounting for the lack of any attempt to descend makes for a lousy conspiracy theory...
