Ladies and Gentleman!

This is what possibly happened  and what is the most logically:

Their plan was to steal all the money and run with all the Bitcoins.
But their plan ran into problems when he got doxed, that scared him and he had to made up some story to save his head and he came up with this "Official Statement" story which have zero logic!
If "Official Statement" story is real then they would say that much before and of course they will post there and interact with people to find solution.

Now he are refunding some balances, to keep people calm and save his head. He is not sending them their whole balance because "they got hacked and don`t have the whole balance" and with that story they will go with the other money (hacked) and hope no one will search them.
