After Eleanor finds out that Vane had Max held and used by his crew, she blacklisted him and his crew from doing any form of business on the Island. Hoping to keep the remaining crew loyal, Rackham goes to to sevreal pirates and captains hoping they will buy their remaining goods. Like everybody else, Gruenwald refuses. Gruenwald says it is because he doesn't even want the chance of Eleanor finding out and punishing him and his ship like she did to Vane.
