Whenever there's an obvious conflict, assume it's not enforced or difficult to litigate or has relatively irrelevant penalties. Experts/lawyers who have a material stake in getting this right have signed off on it. Many (if not most) people with enough status to be on the board of a fortune 500 company tend to also be on non-profit boards. We can go out on a limb and suppose the mission of the nonprofit is not their top priority, and yet they continue on unscathed.
