It depends on what's being compared. Anything that has a known negative effect that is intentionally suppressed in order to maximize profits all fall into the same category to me regardless of that the "it" actually is. At the same time, we have plenty of historical evidence where a new thing was thought to be the greatest thing since sliced bread and rushed to market only to be found that it is pretty nasty stuff. We can now test the new thing much more rigorously if only someone wants to spend the money and possible delay in profits which is no company ever.
