If you write them, be polite; I doubt if any of them reviewed his words before they were posted. Simply ask them if they believe Zumbo represents their thoughts and interests any longer.
BTW, Remington has already come out and said they are immediately evaluating their relationship with Zumbo. I'd expect other sponsors to do the same.
What reputation Zumbo had in this industry is probably ruined forever. He may have published his last words unless he eats a lot of humble pie.
