Hayward, who filed a lawsuit but later withdrew it due to an arbitration requirement, stated that the practice “could harm someone” by unexpectedly draining their battery. He did not specify how many people might have been impacted by the negative testing or if the Messenger testing ever progressed beyond the beta stage. However, Hayward claimed that he was given an internal training document titled “How to run thoughtful negative tests,” which included examples of battery-draining experiments. He alleges that he was fired after three years with the company for refusing to participate in the testing.
