None of the vendors you are mentioning who sell at Daz will back you on this. Daz did not break any laws in buying RDNA . The company was sold by it's owner who now works for Daz as well , are you going to sue her ? They have no obligation to accept any vendor but have opened their arms to many. Your lawsuit is dead in the water. I would save your money and focus on finding a new site to call home and sell your work. You are making more trouble for yourself than it is worth.
