I can sort this out, probably. By that logic, he and you are both correct.
If you go to a store, and buy a game, do you own that game? Yes. You own that copy of the game.
And with that copy, you are free to do what you will with it.
Of course DRG still holds ownership over it, but she gave a copy out, which means that that copy is under someone else's ownership.
Beyond attempt to sort this out, I can't actually comment on it, as I've yet to finish the first one.
