WhatsApp promises it's not Facebook and that it doesn't even want your data

Actions speak louder than words, of course, but WhatsApp today used a few hundred to promise us that it has "respect for your privacy" and that having been bought by Facebook for umpteen-billion-dollars (it was $16 billion) won't go to its head, leading it to steal all your personal data. "If partnering with Facebook meant that we had to change our values, we wouldn’t have done it," WhatsApp's Jan Koum wrote in a blog post.
