Oooh, ive put it up for soon post "expansion", so, legaly, they "released" content people paid for
You forget its EA involved, theyve broken the deal on Makeb, so it means absolutely nothing to them.
Easily they can break every other deal they had and start charging for every tiny piece of content they release. Since by contract you made with them they are not obliged to anything but running servers <service> (and they can close them at any time without even a refund for long term payment option).
