Makeb was only made an expansion when F2P was announced. Before then it was always planned to be a free update. But seems people have short memories, or weren't in the game when it started.
So where is the announcment of it been a content update?
Was it ever actually confirmed and then backtracked on?
If you have no answer to these 2 then you have no argument your just speculating and you dont win arguments that way you win them with actual facts
