Whenever there is a new discovery in any field by humanity, it is human nature to first identify benefits and market it. In due course of time when more and more people use it, we start to see the other side of the invention which are the disadvantages and the side effects.
It is moral and ethical to publish the side effects and disadvantages of the new product. But in order for it to be successful in the market , only the positive effects are promoted. Humans have a huge negative bias and we naturally tend to keep away from pain and discomfort. So it is possible that the product may not sell if people get scared of minor ill-effects of the product. Hence, by default any new invention will be just circulated in common public by showing the positive side and by hiding the negative side. Generally, the true extent of the damage that could be caused by the product would be discovered only after a long time. By then, the damage may be irreversible in few instances.
So beware of this fact before becoming used to any new product, technology or medical drug etc.,
