If i remember correctly it was theMarkyMark. think he was trying to make him say that they fucked up, as they did, and they don't want to admit anything. Also they don't want to say that it is a liquidity problem for (i think mostly binance) exchanges and not security. Because multiple witnesses said that if they start powerdown no one can stop it, and if witnesses hard fork exchanges can just not accept it and nothing can happen to the funds. also freezing the exchanges funds would be the end of the steem blockchain, but Roy was playing stupid and repeating about the safety... he kinda admitted it only when one of the witnesses said he can't withdraw his funds from binance.
