If the poison pill clause is there, what effect does that have on products "Published By Lulu" (or similar venues)?
(Some PoD services provide ISBNs so that products can be sold through Amazon and the book trade, making those PoD services legally the publishers of the books. But how should a prospective
GSL user know if the PoD service acted as publisher of a
3e OGL product - that is still in print - before?)
