honestly, if you are going to change your stance on whatsapp based on facebook's claims and promises now, it's best that you stay on whatsapp. whatsapp has a lot of problems even without the latest changes. one primary issue is the USD 19 billion dollars facebook paid for it. this money has to be recovered and for that it is always going to be a problematic platform. honestly, it was best when whatsapp was charging a dollar or two for a year of usage in early days. though i don't know anyone who paid that money eventually as they kept on extending the free period or something?
