"No True Scientist" would say cigarettes don't cause cancer or co2 emission don't cause global warming, or glyphosate isn't bad for the environment. Yet, it did, for multiple decades.
You have to consider "actually existing science" with it's political and financially directed function, choosing what questions get asked and who will answer them. You can say "oh that wasn't science it was fraud" which is all well and good now but it wasn't for those decades when they served to obscure or bury the truth rather than discover it.
Actually existing science is a really troubled institution and ultimately there is no such thing as science outside of politics, science is part of the political process and cannot escape or be independent of it.
