He trashed talk a journalist immediately after the journalist complained he had to journey thru cold with out heater because his batteries would not last until the next charging point.
He trashed talk the short sellers.
He trashed talk the ones who supported the short sellers.
He trashed talk the ones who might as well be supporting the short sellers, e.g. sec aka shortseller enrichment commission aka security exchange commission.
He is a small guy with a oversized largely sensitive ego.
But most notoriously, he is a terrible public speaker. Like my public speaking teacher would be more ashamed at him than me.
