I think its mostly test of miners - prominent group of tech-related personas have been hacked, so I wonder if they end up asking miners not to validate/approve the list of incoming/outgoing transactions. If they choose to minimize priority of this transactions, they may get delayed over 14 days and eventually fell off a block as never processed bitcoins. Then spender gets their money back. In 14 days they may realize it was a scam. They probably already did!
