Where do bioethicists get their funding?

Bioethic$ Inc. is a very interesting essay pointing out that, increasingly, bioethicists are being paid by the corporations they are meant to be criticising. The trouble is that it's all very well being trained to work out what is right and what is wrong, and telling the companies all about it, but people have to eat and someone's got to pay for it. If not the companies you're talking to, then whom?
