If one person is criticizing Big Pharma because they use shoddy trial methodology when they can get away with it and heavily market minor variations on existing drugs, and another person is criticizing Big Pharma because they're poisoning our blood with fluoride in service to the Illuminati, it's not appropriate to lump them together and say "Big Pharma's critics are in the right."
(Also, I think the idea that they deliberately adopted a weak version of the criticism to argue against is rather conspiratorial - dumb unfounded nonsense gets very popular on the internet all the time! Valuable criticism that requires nuance is memetically disfavored by comparison!)
