MMs are trying to balance their shares issued in last couple of years. They may have issued shares which were not available during the runup. By doing so when the shares sold to the bid they retire that share. Like balancing their shares at the end. This is normal in OTC land. If you really want to hurt them DOC can release the NASDAQ news. So what they got in their balance book is negative shares. So they have to report as negative income. Remember supply and demand.
