The problem with TBI's stance is that he's threatening to publish the information unless Vessenes and Matonis step down, which implies that he won't publish it if they do.
That's not bringing transparency to the activities of the Foundation. If he has evidence of wrong-doing, then he should publish it whether or not Vessenes and Matonis step down. If he doesn't, then he becomes complicit in the "cover up" he alleges is occurring.
He's rapidly becoming the kind of media whore he yesterday accused Leah McGrath Goodman of being. Unless he's willing to publish and be damned regardless of whether or not Vessenes and Matonis step down, then he's not a crusader for truth at all - he's just another egomaniac seeking validation.
