As best I remember, the Lancet published a paper by a drug company that was marketing a treatment for covid, purporting to show that a competing compound, hydroxychloroquine, is ineffective and dangerous. Many scientists wrote in complaining of lack of transparency in the sources of the data in that paper. Authors of the paper started to remove their names from it, and the Lancet retracted it, complaining of corporate interference with science.
That’s why scientific claims should be published in scientific journals like the Lancet. The scientific process of publication, scientific scrutiny, challenge and if necessary retraction worked; a false claim was prevented from proliferating, and the company’s reputation was tarnished.
