If a buyer doesn't know, care, or understand what recasting is they will support sellers who recast. As a group we care, the general public might not. I saw someone comment that we are all copying from Lucasfilm/Disney anyways. And if nobody buys, then nobody would recast.
Buyers have different priorities. If all somebody wants is to get approved and troop, and a recaster is the cheapest path for that, I can't blame the buyer.
