I'd bet that even more dubious science is packaged by large corporate interests. Take Big Tobacco, who had doctors saying smoking is healthy, or the sugar industry, corrupting guidelines and policy on coronary heart disease [1]. And medicine is not immune either, with financial conflicts of interest and pharmaceutical sponsorships correlating with outcomes. [2]
I don't disagree with you, but might provocatively suggest that federal funding in the US vis-a-vis a large university could also be considered a large corporate interest at this point.
