This is the kind of thing I think of when people here on HN try to convince me that glyphosate is safe. When so much money is at stake, corporations naturally try to influence the science, and unfortunately, there are plenty of poorly-paid and/or dubiously-ethical scientists in the world who will take their money.

Under such circumstances I think we have to be massively skeptical of any result that aligns with the business interests in question. When public health is at stake, the burden of proof should fall very heavily on those claiming their product is safe.
