Give the company the benefit of the doubt re communications, IMO. They are in a complicated position, they've been hit with an aggressive short attack that is willing to twist and distort anything they say. They've also been hit with frivolous lawsuits. Their audit has become much more intense than they could have anticipated and they have to do everything they can to ensure the auditor stays focused. And they have fired their weak IR firm and so temporarily have no strategy in the midst of this mess.
Between their lawyers, their auditor, and the IR firms they are likely interviewing, I'm sure just about everyone is telling them that the less they say right now the better. They did flatly refute the allegations - what else is there to say, really? Earnings will be the ultimate statement.
