It's important for people to have freedom to use whatever product they want. We have no problems with other people using other apps, so long as they keep using 'WhatsApp'.
Facebook, Google, Apple, Yahoo - there's a common theme. None of these companies ever sold. By staying independent, they were able to build a great company.
In some countries, WhatsApp is like oxygen.
Everybody who wants to join 'WhatsApp', we'll go out of our way to build a really awesome client for them.
A lot of my time, effort, and focus is spent on 'WhatsApp'. And that, to me, is more valuable and rewarding than to work on anything else.
A lot of what I experienced growing up in the U.S.S.R. and coming to the U.S. as an immigrant actually reflects itself in Whatsapp. Experiences from our youth shape what we do later in life.
