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.
More semantics and misdirection. The planet Makeb was going to be included in a content update, that is the only thing that was said by BW. They never, ever implied that a level cap or anything else would be part of a content update (and free).
