The same question could be asked for the mysterious meteorite Maxima got her powers from. We have no clue why she was chosen and it is unlikely right now that we will get an answer to that question.
This is my outlook basically. Its like the omnitrix. She put em on, they are hers now unless someone with override authority says otherwise. So either the nth dimension azmuth needs to show up, or some other advanced alien able to somehow extract them from her by force. And they clearly have protections, lets see if they have more... active methods of protecting the user.
