There doesn't seem to be any suggestion of fraud in the linked article? Nevertheless if Drs are relying on companies for unbiased data, that again seems like that should be addressed.

I'm not saying there's one point of failure, note in my prior reply I wrote "primarily" their fault. But Drs are the professionals here, they have a duty towards their patients. If a Dr prescribes something for me, I expect them to have weighed up the pros and cons. If Amazon recommends something I have no such expectation.
