I bet its just some block which just turning off tmorph access when it not detecting wow version by which it was released. Don't think its actually that hard to manage "updating" tmorph after ninja patches. Not sure about general new addons and contents, but I guess it's his bonus donation pool. So he doing it as he pleased.
(I'm not against it. He doing great job here after all, it's just I though it would be more pleasurable if we could "fix" ninja patching by ourselves)
