Question: 10 Years On: What do you think of MGSV?

 Kaz and Ocelot really ran Diamond Dogs and that Snake was a glorified operative

I think this was deliberate. After rescuing Miller, Snake basically pleads with him to "tell me what to do, like before" - which can be interpreted as foreshadowing for the twist. Sure, Miller always coordinated over the radio. But the implication is that deep down, Venom was still an MSF subordinate, seeking his commander's orders.

Another thing to consider - it is ambiguous when the post-credits conversation is meant to be happening.  I think it occurred at some point very shortly after Miller recovered from his captivity, while Snake was in the field.  It must have happened before Snake's encounter with Quiet - that was the first of many occasions where Miller attempted to countermand "Big Boss's" authority.  I think that Miller figured out who Venom was (or rather, was not) faster than we were led to believe.  Especially if he remembered that the other Diamond Dogs survivor was the one who lost an arm and took shrapnel to the head, not the otherwise intact Big Boss.

Of course, this is all assuming the ending is indeed real, and I will always consider it ambiguous.
