Why would he need operating income for a site thats been SHUTDOWN??
As far an I am concerned, it doesn't matter what the funds were labeled, he has stolen more than enough bitcoins to make up for his operating funds balance, that balance is the only bitcoin that is touchable as of right now by the owners of glbse and the way I see it is glbse owes a lot of people money right now, that should be distributed properly among the people who glbse owes money to.
So, what would you prefer be done with those funds? Theymos keep them and be liable for distributing them back to customers without any information about balances?
