Yeah, Sony gave Bungie a pretty sick deal. Bungie gets financial backing from Sony and if Bungie doesn't drive itself into the ground they keep their autonomy, and I guess the main benefit Sony got is/was live service expertise from Bungie (which is what Sony was focusing on when they acquired Bungie). The fact that Sony might need to step in is all on Bungie and it shouldn't come as a surprise to anyone who has been keeping up with Bungie. The short gist is that the entire company is horribly mismanaged and that's why they had to lay off and are likely to get taken over by Sony.

And if I'm being honest, I think Sony takeover might be the best thing for Bungie (assuming it doesn't get entirely dissolved). Get rid of the shit management and then, once you've put some reasonable people at the helm, let them do their own thing again.
