They never sold the product. This is Reuters being slimy. The headline and article have been corrected:
Aug 14 (Reuters) - (This Aug. 14 story has been corrected to say that Costco will ‘not sell’ mifepristone instead of ‘stop selling’ the pill in paragraph 1 and removes reference to ‘stopping sale’ in paragraph 2)
This is like being angry at a gas station for never selling prescription lenses because they happen to have sunglasses on a rack in the front. Like, yes people buy reading glasses, and the gas station sells other kinds of glasses. But people tend to go to CVS to buy them so the gas station doesn’t want to carry them and, most importantly, never has in the entire history of their company.
To generate clicks. Outrageous headlines drive engagement back to their site. What percentage of us clicked through and ended up reading something else.
Otherwise Reuters is owned by the Thompson family via Woodbridge investment company. Woodbridge or the thompsons could be buying, selling, shorting shares of Costco or a competitor and are nudging the trading algorithms.
