The only bits of that that seem remotely actionable are the claims that GW shorted stores on their orders, refunded the amount, and required customers to buy direct from them. At least, I think that was the accusation.

And something something not allowing stores to sell via website, or give the discounts they want. But none of that seems like substantial "win me money" actions, as opposed to, "maybe if you've got legal precedent and a sympathetic judge on your side, you can get better contract terms."
