WhatsApp's former CBO Neeraj Arora, who said that he regrets WhatsApp's $22 billion sale to Facebook in 2014, shared a handwritten note by WhatsApp Co-founder Brian Acton, that read, "No Ads! No Games! No Gimmicks!" WhatsApp's other Co-founder Jan Koum used to keep the note taped to his desk. WhatsApp Co-founders quit Facebook a few years after WhatsApp's acquisition.
