Our focus remains on delivering the promise of WhatsApp far and wide so that people around the world have the freedom to speak their mind without fear.

A lot of times, people start out with a lot of good ideas, but then they don't execute. They lose the purity of their vision. You end up running around in circles.

Nobody should have the right to eavesdrop, or you become a totalitarian state - the kind of state I escaped as a kid to come to this country where you have democracy and freedom of speech.

As long as our user base continues to grow, at some point it will have critical mass, and at some point it will tip, and at some point, people will just have to use WhatsApp because their friends are using WhatsApp.

Communication is at the very core of our society. That's what makes us human.

Our phones are so intimately connected to us, to our lives. Putting advertising on a device like that is a bad idea. You don't want to be interrupted by ads when you're chatting with your loved ones.
