Now that I've gotten that out of the way I want to talk about how after generations there are Vidiians who will view all that body part swapping as their culture. Once they are cured there will be underground groups still doing the swapping with each other. Mutual body modification. That's the gentle side of the post-cure Vidiian cultural luddites, there will also be organized crime syndicates where they steal and pirate parts against people's will.
It will be illegal in Vidiian society to exchange body parts but the underground will get around this by keeping themselves covered up and only exchanging non-visible parts. They will shun doctors and any social choices that might involve exposure.
