This is one of the many reasons why any private healthcare model is broken. As soon as there are financial incentives for anything the care of patients, both donors and recipients, is secondary.
I give blood and have a donor card. I do this willingly knowing that I am helping society. If my donated blood or organ was the source of profit for some company, would I donate? I don't know, but I can't see why some company should make a profit out of something I donated.
Private healthcare is a scourge. Nobody should be made bankrupt by illness, or even have to worry about it (financially). In the UK our NHS provides whatever you need, regardless of means - it's just a shame that the current government is in the process of destroying it as a reward to private healthcare companies who funded them at the last election.
