Every time the jury is out on a topic where one side has a vested interest and a billion dollar budget to protect it, you can be reasonably sure what the outcome will be.

See: pesticides and bees, fossil fuels and climate change, food packaging plastics and cancer, pain treatment meds and addiction.

The answer in all those cases is the harmful effects eventually became known, but the jury was out long enough for the vested interests to make a ton of profit and cause a ton of damage which they'll never pay for repairing. All made possible with a series of comparatively small investments to buy scientific research to keep the jury out. The Wikipedia section that the parent post links to straight up says that the only research that found no links was sponsored by Monsanto.

Edit: to be really clear, 'jury being out' refers to scientific consensus. We are not talking about issues where public opinion is uncertain despite scientific consensus, such as vaccines+autism. We are talking about issues where scientific evaluation of some phenomenon is actively prolonged or hindered by vested interests to delay regulatory action.
