These are not in opposition. After following DNDN now, I am quite convinced that your last statement is misleading. Practical considersations about what really motivates people and ethical considersations to insure maximum patient benefit demand we use the best possible tools and create the strongest possible incentives to get accurate and complete information on these products. I would make the same arguments about patent laws against those who want to give things away ( " for ethical reasons"). DNDN is not doing any science and trying to use ignorance and opinion to get its product out the door. If they were even trying to back up the product with data I wouldn't be so critical but nothing they've done lately suggests they really care about accurate and complete characterisataion of the product and nothing will change if they can get it to market in this state.
If you want to use an emotional appeal and talk about ethics, then your next statement should be about getting rid of patent protection. Otherwise, look more carefully at maximizing product value. Unfortunately, practical considersations about human nature require something like an FDA to get people to do science and publish accurate information, not just promotional material.
