Why? You don't know who did it, or why. There's obviously some shenanigans going on from Smith's end, how does he know Georgia has a scholarship available for him? Why would he expect Saban to waive the no transfer within conference rule? Why did he agree to go to Miami and then instead back out and go public with this?
You and I don't know what happened to his stuff and the idea that you demand an explanation from anyone is to believe Smith's version of events entirely. Didn't you already see a picture clearly showing him doing what he claimed he wasn't allowed to do? At this point he just deserves to be ignored, he's not credible.
