Could've, sure, but then they'd be accused of insider trading, or trading against their users or something. With their volume would a death spiral not have happened anyway after all the downward force? You could also see it as them giving their users a chance to get out first. Binance didn't benefit by announcing it either. The token dumped before they liquidated, and they didn't scoop up their competitor.
