Why do they get so much negativity?
Greed

They have a proven track reacord of putting profit above ethics. It's hard to trust when a group would rather pay out damages because it cost less than admitting all the research was for naught. To them a few deaths are about cost balance sheets not human suffering.
To be sure we do get benifets but what is the cost if even one unnecessary death or life long disability is judged ok? It is society and family that pays the price. Those affected can no longer work, their medical costs are now higher and must be paid by someone. In the past before the lobby for be Pharma grew so strong there were better controls and checks for the safety of consumers. Now the Companies use wants and desires of the consumers to decide what they will develop instead of science. For example, Viagra, Yaz, and other drugs that were developed because that's what consumers want and will willingly pay for. Yaz was a bad drug, so were many others recently pushed out too quickly. The companies pay doctors to push the drugs, and direct market to the consumers get your drugs just ask for it by name and you will have a happy life on a beach.
Personally I don't believe profit should be above safety. I don't believe in advertising medicine. It's one thing to have the info out there and accessible but presented objectively with all of the study results available not just the adjusted studies and it's a completely different thing when it is being marketed. Yes research is expensive but so is the cost of bad drugs dumped out there too quickly and then recalled after the big Pharm recoups there reaserch cost. They still come out ahead after paying damages. But they are doing long term damage by destroying people faith that drugs are life saving and good by putting their immediate greed ahead of humanity.
