> Acton told Forbes that he left over a dispute with Facebook regarding monetization of WhatsApp, and voluntarily left $850 million in unvested options on the table by leaving a few months before vesting was completed. (Source: Wikipedia) I am not even sure what this means but it does not change the fact that he co-founded whatsapp and he did sell it to Facebook in 2014 and it was very clear even back then that they had no good intentions. Also, he IS filthy rich even without these 850 million.
