Perhaps a majority of binance customers doesn't know or care what's going on. They will bitch if and only if they try to withdraw Steem and can't because Binance is lacking the liquidity to do so. Just like ordinary people won't bitch that the bank is lending their savings to other parties (but will bitch if the bank is unable to fullfil it's obligations), airline passenges won't bitch if the flight is overcommited (but will bitch if it's actually overbooked and they are the unlucky ones that won't be allowed on the flight), etc.
