They'd probably screw up the free member features while boosting up the premium member features.Free of charge? I doubt that.
But that just means that if MU really does truly come back, it would have less competitors. Which is a good or bad thing depending on someone's point of view.Thing is, the authorities already got what they wanted. A lot of the other file hosting sites went down when Mega was taken down. Filesonic and Wupload to name a few. While yes, if Mega were to never come back other sites will take it's place, the data that are being held by Mega, some of them could never be found other than there.
