Theranos is a prime example of a company being unethical to its consumers. Started by Elizabeth Holmes in 2003, she created a product that was suppose to revolutionize healthcare by being able to detect health problems with just a couple drops of blood. This product was supposed to be cheaper and more convenient and readily assessable for any consumer. After years of dodging and fibbing information about the device, they were finally exposed of using other lab materials and denied any accusation of it, as well telling consumers wrong health information leading them to believe they had issues that weren’t true. Over all, this company did a lot of terrible things and thankfully there was a whistleblower to prevent anymore false claims.
