As to the point of donors suing to get money back.... I don't see that being something very many Axanar donors will pursue. Perhaps one or more of the three who contributed $10,000?
if the AG goes after them, my non-attorney browsing of news about similar cases is that they don't have to have a large number of donors go after them, just enough to validate the complaint. aside from patches etc those who were to get benefits from the actual movie production having gone forward might be in that class. how can Axanar offer for big bucks to give credits in a film if they start asserting they never actually intended to deliver the film? It looked to me from the other cases like an AG case would be the equivalent of a class action lawsuit in scope.
