Scientific community is just people. Some people will be brave and say something, most will tow the party line (where the money comes from) and not make waves. It is at personal cost when something that goes against the narrative is espoused.

Yes, I find it amazing how few in the medical profession are willing to speak up. Is it because they are not exposed to the info, relying on the news media? Or is it fear of lack of income from being canned. And I find it amazing that politicians are so ignorant of the truth. Is it laziness or just once again relying on the fake news media for their "facts". Of course many are bought and paid for, eh.
One problem with the Go-Along-with-the-Herd tactic:
Tell too many lies to a customer/client/patient and they'll quickly become an EX customer/client/patient.
