I'm against all organ "donations". If it is your time to die, it's your time to die. Also, the biggest issue in organ donation isn't china or taiwan supposedly harvesting a few dozen prisoners' organs. It's the illegal trafficking of organs of poor and desperate people around the world which makes up almost all of the organ harvesting/donations.
I'm going to bet that almost all of the organ harvesting in china, taiwan and most of the world is organ "donations" by poor people. Now that's what people should truly be upset about. But I'd doubt we'd see much propaganda about that.
I agree that paying for organs creates bad incentives. But I think organ donation after (non-capital punishment) death is a Good Thing, and it's hard for me to understand someone being against it.
By the way, prisoners in Taiwan can still voluntarily donate their organs to their close relatives.
Trying to mix Taiwan and China together is quite a word salad.
