Well, I have been reading what others have said, but my understanding is anything with the D20/
WOTC logo's on it must be sold off or destroyed by the time the license is terminated.
So if that is false, then yeah, this is a moot question.
However suing a corporation isn't expensive if you know how to file a lawsuit. ITs expensive to keep up with all the shenanigans the expensive lawyers pull to make lawsuits go away without actually going to court.
